How to restrict web browsing using firefox

You might have heard about WebRTC leak and ways to prevent it. WebRTC is often talked about on VPN websites. What exactly is WebRTC and what’s the havoc it causes?

WebRTC is a technology that allows your browser to have video and voice communication abilities. It might seem like an annoyance when you think about the leaks it causes, but it’s actually a great technology.

When you use Google Meet to hold a video conference, you’re using WebRTC. The same is with the Facebook Messenger video call. There are other applications that make use of WebRTC. For example, if you’re on Discord, you use WebRTC.

Basically, if you’re voice or video calling on your browser, you’re using WebRTC. Without this feature, your browser will be severely limited in its abilities. And with this feature, you don’t need any extra plugins for voice and video communication.

All major browsers (Mozilla Firefox, Google Chrome, MS Edge, Apple Safari, Opera, etc.) come with WebRTC capabilities. In fact, it is used in many mobile apps as well. It is a completely free technology and is open source. Since it is open source, it is improving and evolving to offer better services.

It enables live communications in real time.

Now, what is WebRTC leak?

WebRTC works by sending audio/video feeds between two entities. For this, it established communication channels from the browser to the website you open. This means your browser will share some of your information with the website, which will include your IP address. And these channels can bypass the encrypted tunnel you have setup. So basically, a WebRTC leak can reveal your real IP address even if you are using a VPN.

Imagine this scenario: You’re using a VPN and want to have a voice call with someone so you need to use WebRTC. But it will leak some data so your real IP will get shown on the website side. This beats the entire purpose of using a VPN. A channel that bypassed the tunnel you’ve created – it’s scary.

How to know about a WebRTC leak?

To see if your IP is leaked, just connect to a server and run a leak test. If you see your real IP on the website, your IP is being leaked. But if you can see the IP address of the VPN server, you’re safe and your browsing is secure.

What to do if your WebRTC is leaking your details?

The good thing is that WebRTC leaks can be blocked.

Here’s how you can block the WebRTC leak

There are many ways to block the WebRTC leak. One way is by getting a VPN that doesn’t allow these leaks. These VPNs will let WebRTC work but only through the encrypted tunnel.

Another option is to block the WebRTC requests directly from the browser. You can also use browser extensions if you cannot disable WebRTC.

Keep in mind that if you disable WebRTC, you won’t be able to enjoy the functionalities that come with it.

Disabling WebRTC in Chrome

You cannot disable WebRTC in Chrome. The only thing you can do is use add-ons. A good Chrome add-on is WebRTC Leak Prevent which is fast and powerful. It controls the hidden WebRTC settings and protects you against the leaks. Of course, when you use this, you won’t be able to use a WebRTC based service.

How to restrict web browsing using firefox

The top story in tech last week was Microsoft’s decision to give up on the EdgeHTML engine and switch to Chromium for Microsoft Edge, which essentially means that the software giant is building its very own Google Chrome browser.

While work in this regard is still in its early days, and a preview of the new browser would ship in early 2019, some are already worried that the lack of options in the browser world could give Google too much power.

Mozilla’s CEO, for instance, has warned that Microsoft migrating to Chromium is already a step in this regard, emphasizing that Firefox would pretty much remain the only powerful alternative to Chrome.

Having multiple browsers on a system, especially at home, is something pretty common for today’s Internet users, especially on Windows 10 where the operating system comes with Edge pre-installed.

And given the migration to a new Chromium engine, some IT pros might want to set up additional restrictions on the Windows 10 devices they manage, including blocking Internet access for third-party browsers.

Setting this up isn’t really rocket science, and it all comes down to creating a new rule in the Windows Firewall.

If you’re not familiar with the Windows Firewall, it’s one of the tools embedded into Windows 10’s security feature arsenal, and it’s quite a handy solution that provides the essential tools for controlling incoming and outgoing traffic.

In this case, what you need to do is to create a new rule for Google Chrome and Mozilla Firefox, so that the two processes would be blocked from accessing the Internet.

How to restrict web browsing using firefox

To do this, launch the firewall by simply typing Windows Firewall in the Start menu.

Then, you need to create the rule, so on the right pane, click the option that reads New Rule and select the Program option. This needs to be done for Chrome and Firefox individually, so you’ll have to repeat the process for each browser.

Click Next to advance to the next step and then select This program path and click Browse:

By default, these are the processes and the location of Google Chrome and Mozilla Firefox – note that they may differ if you installed the browsers in a different location of your system, so you need to point the firewall to the main process:

Mozilla Firefox: firefox.exe
C:\Program Files\Mozilla Firefox

Google Chrome: chrome.exe
C:\Program Files (x86)\Google\Chrome\Application Once you provide the path to the process that you want to block, click Next to advance to the next screen and then select the option that reads Block the connection.

In the next step, you’ll have to choose the networks where the new rule would be valid, with three options offered, namely Domain, Private, and Public. Check all of them and then click Next once again to choose a name for the rule. When you’re ready, click the Finish button and that’s it.

How to restrict web browsing using firefox

The new rule should then be displayed in the Outbound Rules pane, so if you want to edit it at a later time, you just need to double-click it. Removing it is also possible to allow any browser to access the Internet according to the default settings.

The same tutorial can be used for pretty much any other app on your system that requires access to the Internet, but the Windows Firewall also provides an additional tool that offers even greater control of your connections. You can also block the port should you want to restrict access for a specific type of app.

Rebooting the system isn’t required, as the new firewall rules are applied immediately just after setting the policy.

Do you ever wonder how most browser-related problems are often easily resolved by purging cache data? That’s because the difference between the cached version of the web page on your computer and the version that you’re loading from the web often leads to errors and glitches. This ends up ruining your overall browsing experience. So what’s the solution? Well, if you’re tired of hard-refreshing your browser because it’s showing an outdated web page or you’d just like to steer clear from reoccurring browser issues, we’ll show you how to disable cache in Google Chrome and Firefox on your PC.

How to Disable Cache in Google Chrome

There’re a couple of ways you can go about disabling cache in Chrome. You can either use the Developer tools in Chrome or a third-party extension to disable cache instantly. Here’s how to do both.

1. Use Developer Tools

As the name suggests, Developer tools are often used by developers while creating and testing software. These tools give them access to the internal workings of a web browser. That said, a normal user like you and me can also take advantage of this tool to prevent Chrome from caching web pages. Here’s how.

1. Launch Google Chrome on your PC and use the three-dot menu in the top right to navigate to More tools > Developer tools.

How to restrict web browsing using firefox

Alternatively, you can also use the shortcut Ctrl + Shift + I on Windows or Command + Option + I on Mac to launch Developer tools in Chrome.

2. Switch to the Network tab and mark the box that reads Disable cache.

Now as long as the Developer Tools window is open, Chrome will not store any new cache data.

2. Use Extensions

While the above method works seamlessly, it does require you to keep the Developer tools open which ruins the browsing experience. Luckily, there’s a better way to disable cache in Chrome, which involves using a third-party extension.

There are a bunch of extensions in the Chrome web store that can clear cache with a single click, but only a few can prevent Chrome from storing cache data at all. Among them, Classic Cache Killer is definitely a reliable option.

Once you’ve added the Classic Cache Killer in Chrome, you can prevent Chrome from storing cache data by simply enabling the extension.

How to Disable Cache in Firefox

Firefox belongs to one of the rare breeds in the browser community that is not based on Chromium. In spite of that, Firefox too carries a similar Developer tools menu along with some hidden settings that you can tweak to disable cache with ease. Read on to learn how.

1. Tweak Firefox AutoConfig

Firefox has an advanced menu that you can use to customize your browser experience. This menu also includes an option to disable cache in the browser. Here’s how to access it.

1. Open a new tab in Firefox. Type about:config in the address bar at the top and press Enter. Next, click on the Accept the Risk and Continue button to proceed.

2. Now type in browser.cache.disk.enable in the search box at the top and double-click on the result that appears to change its value to false.

How to restrict web browsing using firefox

Now close Firefox and open it again. Repeat the same steps above to change the value of browser.cache.memory.enable to false.

And that’s about it. Firefox will no longer store any kind of cache data on your PC.

2. Use Developer Tools

Similar to Chrome, you can also disable cache in Firefox by visiting the Network options inside its Web Developer menu. Here’s how.

1. Launch Firefox on your PC. Now click on the three horizontal lines in the top right to navigate to More tools > Web Developer Tools.

How to restrict web browsing using firefox

2. In there, switch to the Network tab and tick the Disable Cache option.

How to restrict web browsing using firefox

That’s it. Now Firefox will not save cache data anymore unless you close the Developer menu.

3. Try Add-on

Alternatively, you can also get an add-on to enable and disable cache with a single click. Try Toggle Cache that allows you to disable cache with ease.

Why You Should Disable Cache in Your Browser

The obvious advantage of disabling cache is that the browser won’t save any version of the web page. So, you’re guaranteed to get a fresh copy of the web page every time you visit it. For instance, developers often disable cache while making changes to the website or a web app so that they can see the changes they’ve made in real-time.

Why You Should Not Disable Cache

If you’ve disabled cache, your browser will be forced to load each element of the web page every time you visit it. This means that it’ll require more time to load web pages. For instance, when you visit TW, certain elements such as the logo appear on every page in the exact same location. When you allow your browser to cache web pages, it doesn’t have to download that logo every time you read a new article. This helps your browser save bandwidth as well as loading time.

Wrap Up: Disabling Cache in Google Chrome and Firefox

Ultimately, it all comes down to personal preference. If you want to avoid running into browser problems and you’re okay with your browser taking a little longer to load webpages, you can use any of the methods above and prevent your browser from caching web pages.

So many ads, so little patience… It’s time to stop the madness.

The average person sees an average of 4,000 ads a day. If you think that’s too many, an ad blocker is your new best friend.

An ad blocker is a piece of software that can be used to block ads, and they work in two ways. The first way is when an ad blocker blocks the signal from an advertiser’s server, so the ad never shows up on your page. Another way ad blockers work is by blocking out sections of a website that could be ads.

These ads might be loud video ads, ads that follow you around the web, trackers, third-party cookies, and more. To use an ad blocker, you can search for ad blocker add-ons that are available in your browser. Firefox, for example, has this list of approved ad blocker add-ons. Click on this list (or ad blockers that are approved for your browser) and see which fits your needs.

Download Firefox — English (US)

Your system may not meet the requirements for Firefox, but you can try one of these versions:

Download Firefox — English (US)

  • Download Firefox
  • Download Firefox
  • Download Firefox
  • Download Firefox
  • Download Firefox
  • Download Firefox
  • Download Firefox
  • Download Firefox
  • Firefox for Android
  • Firefox for iOS

Find the right ad blocker for you

There’s AdBlocker Ultimate that gets rid of every single ad, but buyer beware. Some of your favorite newspapers and magazines rely on advertising. Too many people blocking their ads could put them out of business.

Popup ads are the worst. Block them with Popup Blocker and never deal with another annoying popup again.

One of the most popular ad blockers for Chrome, Safari and Firefox is AdBlock. Use it to block ads on Facebook, YouTube and Hulu.

Create a tracker-free zone with Content Blocking

On Firefox, you can use Privacy or Content Blocking settings to get even more control over ad trackers that serve you the ads.

How to restrict web browsing using firefox

Choose your level of protection

To start, click on the Firefox menu in the top right-hand corner of your screen. It looks like three lines stacked on top of each other. In the drop-down menu, click on Content Blocking. You should see a blue pop-up with different selections.

Go easy with Standard mode

If ads don’t bother you and you don’t mind being followed by trackers and third-party cookies, then the Standard setting should work for you. To get trackers off your tail in Standard mode, use a Private Browsing window.

How to restrict web browsing using firefox

Get tough with Strict mode

If seeing too many ads ruins your day, then the Strict mode is a better fit. This mode will block known third-party trackers and cookies in all Firefox windows.

Do-it-yourself Custom mode

The Custom setting gives you the ultimate choice. You can decide what you’re blocking, including trackers, cookies and more. If you allow cookies from a website, you’ll automatically be in Custom mode.

How to restrict web browsing using firefox

Cover your trail, block trackers

Click on the Trackers box and you’ll be able to block trackers in two ways. One way to block trackers is to do it when you’re working in a Private Window. Another way to do it is to block trackers in all windows. Keep in mind that if you choose to always block trackers, some pages might not load correctly.

Take a bite out of cookies

Cookies are sent by websites you visit. They live on your computer and monitor what you’ve been doing on a site. When an airline hikes your rates because you’ve looked at plane tickets once that day, that is the handiwork of a cookie.

In Firefox, you can block all third-party cookies or just those set by trackers. Be aware that blocking all cookies can break some sites.

How to restrict web browsing using firefox

Send a Do Not Track signal

If you don’t want your online behavior used for ads, you can send websites a polite “thanks but no thanks” letter by checking the Do Not Track option of Firefox. Participation is voluntary, but the websites that participate will stop tracking you immediately.

Speed up thanks to ad blockers

In some cases, an ad blocker can help your browser go faster. When an ad is loading, it can slow down a website. At the same time, it takes longer to find what you’re looking for if you’re too busy closing yet another ad.

If you want to learn more about ad blocking, there are hundreds of ad blocker extensions available for Firefox and other browsers. If want to try out the ad blockers Firefox uses, click here to download a browser that puts privacy first.

Private Browsing is one of the essential features of major modern web browsers – let it be Google Chrome, Firefox or Internet Explorer. In all of them, however, the feature may be known by different names, though. For instance, if we take the case of Google Chrome, the private browsing system is known as Incognito. If we come to the case of Internet Explorer, it’s known as InPrivate Browsing. Obviously, you might have used the features in several instances.

How to restrict web browsing using firefox

We will have a look at the instances when private browsing is useful. Suppose you want to search for a few results without including personal results. Or, you may want to browse some websites without letting others know. It’s common if you are using a public computer, because you don’t have to mess up with any type of stored data. In other words, it’s like a close-and-forget web browsing session to count on. Despite having all these advantages, there are times when you will have to disable Private Browsing in these browsers.

Suppose your kids are using the mode for hiding what they browse. Alternatively, you may want to prevent other strangers from using your internet resources. In all these cases, you will have to turn off this feature — so that everything and anything is recorded on your system. Today, in this article, we have come with step by step guides to disable private browsing in Chrome, Mozilla Firefox and Internet Explorer. Shall we start?

How to Disable Incognito Mode in Google Chrome?

There is no default option to disable Incognito Mode in Google Chrome. To make that possible, you need to use a third-party extension. Don’t worry; we have an awesome Windows-based extension to use namely Incognito Gone. Just follow the steps from below section to disable this option.

One thing to be noted here is that Incognito can help you disable private browsing in four different browsers — Google Chrome, Internet Explorer, Mozilla Firefox and even Microsoft Edge. That having said, you have a complete freedom to use the dedicated methods if Incognito Gone does not work well. Here, however, we

  1. First you have to download and install Incognito Gone from Here
  2. Run the installation file and you would see the simple dashboard on the screen.
  3. There are three options on the screen, each one for Chrome, IE and Firefox.
  4. Now that we want to disable the option in Chrome, you can hit the button

Just re-open your Chrome browser and the Incognito mode won’t be available for use. Yay, we have done it right. This is pretty simple too.

How to Disable InPrivate Browsing in Internet Explorer?

As we said, InPrivate Browsing is the name for browsing privately via Internet Explorer. We don’t really know how many of you are actually using Internet Explorer for browsing. Well, if you are using that, you have an in-built option to disable the option, from Windows itself. You just have to follow the given-below steps to get that task done.

We are going pretty brief here. This method requires no previous technical knowledge, whatsoever.

  • First, you have to open Group Policy Editor function of Windows. You must have a compatible version to use this feature. To open it, you’ve to open the Run box and type gpedit in the given column. Hit enter to move on.
  • Go to Computer Configuration and select Administrative Templates
  • Choose Windows Components à Internet Explorer à Privacy
  • Now, you can see a list of options in the right section of the page. Select Turn off InPrivate Browser and double-click to move forward.
  • In the upcoming window, select the option named Enabled and hit the Apply button to proceed.

Go back to Internet Explore and you won’t see InPrivate Browsing in the options. By the way, if you cannot work with this method, there is another method via Windows Registry. To follow that, you can follow steps we have given below.

  1. Open Registry Editor in your Windows PC
  2. Search for the key we have given below
  1. Right click on the screen and choose New
  2. Select DWORD
  3. Set value as 0

This method would work no matter what.

How to Disable Private Browsing in Mozilla Firefox?

There are many Mozilla Firefox users who want to get rid of the Private Browsing feature. Here too, you will not find a default option to do that. Therefore, you will have to use a Mozilla add-on named Disable Private Browsing Plus. It’s a multipurpose add-on, because it does a lot of jobs. For instance, once installed, you will not find options for deleting Browsing History too. if these are fine, you can get started with following steps.

  1. Download Disable Private Browsing Plus from Mozilla Add-Ons Website.
  2. Install the plugin.

With these steps, you can get rid of the Private Browsing feature in no time. However, at a point, if you like to re-enable the Private Browsing feature, you have to uninstall the aforementioned extension from PC.

We hope the step is so simple than you had expected. Alternatively, you can use the all-in-one method we’ve given for disabling the same feature in Chrome.

Summing Up

These are some comprehensive methods to disable private browsing in Google Chrome, Mozilla Firefox and Internet Explorer. There is also another solution that fixes all the three problems. It’s up to you to choose. If you are using Firefox on Chrome, we recommend using the add-on. Choose the right option and proceed for a transparent web browsing experience in your PC.

It’s time to start using Firefox’s solid collection of content-blocking tools.

How to restrict web browsing using firefoxMozilla

Tired of leaking data across the web? The Firefox browser and its privacy tools can help protect you and your data as you visit websites. Among the threats Mozilla’s Firefox web browser for Windows and MacOS can protect you from are trackers that gather your browsing history, cryptominers that secretly use your device’s resources to mine cryptocurrency and fingerprinters that uniquely identify you based on your device, settings and apps.

A fingerprinter is an especially stealthy tool that websites and advertisers use to build a specific profile of your online activities, using subtle hints your browser leaves on websites you visit. Factors include which browser you use, which extensions you’ve installed, your networking configuration, your device’s time and your wireless settings. In essence, you’ve left your “fingerprints” all over your browsing activity.

Taken all together, these small bits of information can form a unique set of characteristics about you and your machine that can advertisers can use to identify your individual device and track you across the web without your permission.

Here’s how to protect your privacy using Firefox’s privacy and security settings.

How to use Firefox’s content-blocking tools

Firefox 69 can protect you from websites that gather information about you without your consent as well as from cryptominers and fingerprinters. You can check which version of Firefox you’re running by selecting About Firefox from the Firefox menu.

Because blocking trackers can also cause some sites to break, Firefox lets you choose among privacy settings to find a balance between protection and usability.

1. From the Firefox menu, choose Preferences. (You can also get here by clicking the hamburger menu on the right side of the toolbar and choosing Options on Windows and Preferences on MacOS.)

2. In the preferences window that opens, click Privacy & Security.

Use Firefox’s Privacy & Security settings to set your browser protection.

3. Choose which privacy setting you want to use:

  • Standard protection blocks trackers in private windows, third-party tracking cookies and cryptominers.
  • Strict protection blocks trackers in all windows and fingerprinters along with third-party tracking cookies and cryptominers.
  • Custom lets you fine-tune how you want to block trackers and cookies.

4. After you make your selection, a Reload All Tabs button will appear. Click it to apply your new tracking setting.

Note: You may want to tweak your privacy settings if you find that some of your favorite sites behave strangely after you block trackers.

You can also turn on Do Not Track here to signal to websites you don’t want to be tracked, but sites don’t have to honor your request, and in fact turning on Do Not Track can be one of the bits of information advertisers use to fingerprint your browser. If you want to take the next step in guarding your privacy, you can look at using a VPN and check which permissions you’re giving apps.

In Firefox, how do I do the equivalent of –disable-web-security in Chrome. This has been posted a lot, but never a true answer. Most are links to add-ons (some of which don’t work in the latest Firefox or don’t work at all) and “you just need to enable support on the server”.

  1. This is temporary to test. I know the security implications.
  2. I can’t turn on CORS on the server and I especially would never be able to allow localhost or similar.
  3. A flag, or setting, or something would be a lot better than a plugin. I also tried:, but something must be wrong since my requests come back as completely empty, but same requests in Chrome come back fine.

Again, this is only for testing before pushing to prod which, then, would be on an allowable domain.

Almost everywhere you look, people refer to the about:config and the security.fileuri.strict_origin_policy. Sometimes also the network.http.refere.XOriginPolicy.

For me, none of these seem to have any effect.

This comment implies there is no built-in way in Firefox to do this (as of 2/8/14).

From this answer I’ve known a CORS Everywhere Firefox extension and it works for me. It creates MITM proxy intercepting headers to disable CORS. You can find the extension at or here.

I have not been able to find a Firefox option equivalent of –disable-web-security or an addon that does that for me. I really needed it for some testing scenarios where modifying the web server was not possible. What did help was to use Fiddler to auto-modify web responses so that they have the correct headers and CORS is no longer an issue.

If on https go to menu Tools -> Options -> Https and tick the Capture & Decrypt https options

Go to menu Rules -> Customize rules. Modify the OnBeforeResponseFunction so that it looks like the following, then save:

This will make every web response to have the Access-Control-Allow-Origin: * header.
