Do I really need a VPN on my Firefox browser?

Using a VPN extension on your Firefox browser is a very good idea. After all, a good one should deliver a lot of the same benefits included in a VPN desktop app, so it will improve your online security. Although it’s only a browser extension, it should still hide your IP address, and it will stop your online activity from being tracked by your ISP or other third parties. It can also allow you to unblock geo-restricted content on streaming platforms.

Some will even connect automatically, so you don’t need to remember to connect to a VPN every time you go online. And because it’s an add-on, it will likely be a more lightweight option that will consume fewer resources than the desktop app. It should also be easier to use than the app version, with fewer confusing options and features. So it can be a good choice for beginners.

Having said that, if you want to use a VPN for more than just browsing the internet, you might be better off using the desktop app. This will give you access to a lot more features. And it will deliver much more robust privacy measures. So, if protecting your online identity is a big concern of yours, we would recommend sticking with the desktop app instead.

How to set up a VPN addon on Mozilla Firefox?

Setting a VPN extension for your Firefox browser is a great step towards secure browsing. Choosing the best VPN extension for Firefox will also guarantee you the most efficient security. Thus, in this case, we would recommend NordVPN. It provides you with HTTPS to protect your traffic and it has the Threat Protection Lite feature too which blocks ads and malicious websites.

Let’s see how to set up a VPN extension on Mozilla Firefox:

1. Download the extension from the Firefox website for extensions
2. Click “Add to Firefox” to install the extension

3. Click “Add” after getting prompted with permission for the extension

4. Check this and hit “Okay” to allow the application to run in a private window

5. When the installation is complete, the NordVPN icon will appear on the Toolbar on the top right corner of the Firefox browser

6. Click on the NordVPN logo
7. Choose to "Log in" or "Sign up" if you don’t have an account yet
8. After signing in to your account, you will be able to use the feature "Quick connect" or choose a specific server by clicking "Connect to a specific country"
9. After connecting to a server, the NordVPN logo on the toolbar turns green which indicates that your connection is secured. Now you can enjoy safe browsing!

Is it safe to use a VPN add-on on Firefox?

Yes, so long as you’re using a reputable VPN, such as NordVPN, it’s perfectly safe to use a VPN browser extension on Firefox. A decent VPN add-on will give you some protection by keeping your online identity private, including your IP address. It will also stop hackers and other third parties from being able to track your online activity, including what websites you’re visiting and what you do while you’re on them.

Having said that, VPN browser extensions don’t have as many security features as VPN desktop apps. After all, it’s worth noting that a good VPN extension will only protect your online traffic while you’re using your browser. Some VPN browser extensions won’t encrypt your connection at all. So it’s worth bearing that in mind before you set up your add-on.

On the other hand, a VPN desktop app will protect all your internet traffic from your PC. So, provided you’ve chosen a reliable VPN, your online information will remain completely safe from prying eyes.

But it’s important to be aware that not all VPNs are as safe as they seem. In fact, some free VPN apps can actually make your data less secure.

How a VPN can help with WebRTC leaks?

A WebRTC leak is when your public IP address is exposed via the browser’s WebRTC functionality. This means that your IP address is disclosed to any site and hackers are able to access your sensitive information.

If you end up with a WebRTC leak, then getting a VPN is the best option. It is able to block any unwanted IP address leaks through WebRTC while allowing authorized connections to continue under your VPN-provided anonymous IP.

See how to check for WebRTC leak and find out if your real IP address wasn’t exposed:

1. Disconnect and exit the VPN that you are connected to
2. Type in “What’s my IP address” into Google to find out your original IP address and write it down
3. Exit your browser
4. Re-launch your VPN and refresh the webpage. Attempt step 2 once more
5. If the displayed IP address is the same as it was before step 4, then it means a WebRTC leak is exposing your original IP address.

Can I use a free VPN for Firefox?

While it’s technically possible to use a free VPN with a Firefox extension, it’s certainly not something we’d recommend.

Free VPNs usually make money by tracking customers’ online activities and selling the information to third parties. And as if this wasn’t enough to put you off, free VPNs offer much slower speeds. And they often can’t unblock region restrictions on international streaming services.

If you really want to use a free VPN, you’d probably be better off using a freemium. This is a free version of a paid VPN that will usually have much more limited functionality than the paid-for option. They can’t unblock geo-restricted content, and they don’t offer as many security features. Freemiums also tend to come with data caps, so they’re not suitable for anything more than light web browsing.

If you do want to give it a go, however, we’d recommend trying Windscribe’s freemium option. It comes with access to a reasonable number of features, and it has a fairly high data cap of 10GB a month.

Alternatively, most paid-for VPNs offer a free 30-day money-back guarantee. So if you only want to use a VPN in the short term, you could try it out for a month and then claim your money back.

Conclusion

Lots of VPN services have really useful browser extensions for Firefox. They tend to be a lot more lightweight than traditional VPN desktop apps, so they come with plenty of advantages. It uses up fewer resources and offers faster connections, and it can use a different browser for regular, direct connections.

After thorough testing we can say the tools on this list will be great inside and outside of Firefox!
