Best VPN Extensions for Mozilla Firefox

Mozilla Firefox LogoIf you have been on the internet for a while, you may vaguely remember a browser called Netscape Navigator/Communicator. If so, you may also know that the original company, Mosaic, released their code and formed the company called Mozilla. It is a combination of Mosaic and Godzilla. Of course, Mozilla rewrote all the code and released Firefox. It does not have the same market share that Google Chrome has. However, there are a number of users that argue it is a more secure browser. All versions of Firefox allow extensions. That is great whether you browse on your PC or mobile device. The problem is, there are many different VPN extensions to use. Because of that, it may be hard to pick the right ones. We can help you choose the best option for your needs. These extensions will work for Android and iOS as well.

Disable WebRTC addonThe final extension we suggest getting is called Disable WebRTC. We have noticed that the first four VPN extensions already have some sort of WebRTC protection. However, the last one does not. Also, if you decide to try any others, they may not either. The purpose of this extension is to block WebRTC. If you choose not to, any website you visit will see your real IP address anyway. To get this one, go to the three horizontal lines in the top right-hand corner and click on them. Then, select the “Add-ons” section. Now, click on extensions and type in “Disable WebRTC”. Once you find it, click on “Add to Firefox”. Once it is added, close Firefox and re-open it. Though you may not see it in your toolbar up top, you can verify it is still there. You are now protecting yourself against WebRTC leaks. You can visit doileak.com to test for a wide range of leaks.
