Firefox Won’t Run With Vpn? Here’s How to Fix It

Here we can see, “Firefox Won’t Run With Vpn? Here’s How to Fix It”

  • Mozilla Firefox is one of the most widely used web browsers nowadays.
  • To preserve your privacy, you should utilize a VPN in conjunction with your browser.
  • However, your VPN may not work in all browsers on your Windows PC at all times.
  • The remedies below might assist if you have problems using Firefox while connected to a VPN.

You’ll need to be unique to beat Chrome in the browser competition, which is still the most popular option. With the fast Quantum version, Mozilla made a lot of beneficial modifications, but it appears that some VPN-related issues have developed since then. While using Mozilla Firefox with VPN enabled, some users have had difficulties.

As a result, we’ve outlined a few actions that should assist you in dealing with this. If none of the methods work, we recommend submitting a support ticket to your VPN provider. Meanwhile, please take a look at the instructions we’ve supplied below.

In Mozilla Firefox, how can I resolve typical VPN issues?

1. Verify your connection settings

Let’s be sure the connection isn’t the one causing the Firefox experience to be ruined before we move on to a more internal approach to the problem. The simplest and most obvious method is to experiment using a different browser in conjunction with your VPN to see what happens. Also, if your Firefox VPN addon isn’t working, try removing it and reinstalling it.

Continue with the steps below if everything is working correctly, but the Firefox + VPN combination isn’t. If you can check that the internet is completely turned off, however, take these methods to fix it:

  1. Restart the computer.
  2. Your router and/or modem should be restarted.
  3. Make use of a hardwired connection. It’s a lot more stable now.
  4. Examine your network drivers. Check that they are correctly installed in Device Manager.
  5. Run the Windows Troubleshooter program:
    1. Open Settings by right-clicking Start.
    2. Security and open updates.
    3. From the left pane, choose Troubleshoot.
    4. Click the “Run the troubleshooter” button under Internet Connections.
  6. Using the Command Prompt, reset your IP address:
    1. Type cmd in the Search bar, right-click Command Prompt and select Run as Administrator.
    2. Copy and paste the following lines one by one into the command line, pressing Enter after each:
      • netsh winsock reset
      • netsh int ip reset
      • ipconfig /release
      • ipconfig /renew

Continue with the steps below if everything is working as it should and your internet connection isn’t to fault for the Firefox/VPN issues.

However, we’d like to point out that, in most cases, it’s not the browser that’s to blame: VPN compatibility can also be an issue.

3. Delete your browser’s cache

Regardless of how much it affects overall speed and reduces page loading time, a bloated browser cache can bring a slew of problems. That’s a good enough excuse to clean everything up and start over. We can’t say for sure whether it is or isn’t causing the VPN issues, but it’s a standard troubleshooting approach.

If you’re not sure how to clear cache in Mozilla Firefox, follow these instructions:

  1. Launch Firefox.
  2. To open the Clear recent history dialog box, press Ctrl + Shift + Delete.
  3. Select Everything from the Time range to clear the drop-down menu.
  4. Make sure the Cache box is checked. It’s entirely up to you whether or not you want to keep the rest.
  5. Clear Now should be selected.

Take a look at the next step if you’re still staring at a blank screen.

4. Install the latest versions of Mozilla and VPN

With the advent of Firefox Quantum, Mozilla decided to step up its game and modify many things. Firefox Quantum is not supported by all VPN systems (those with browser extensions).

Furthermore, as you read these paragraphs, their separate developers are most likely working on optimizing the brand new browsing solution. As a result, check sure your VPN and Firefox are both up to date.

Mozilla Firefox and any current browser extensions are automatically updated, but if your Firefox VPN isn’t working, you should double-check that everything is up to date. If you’re not sure how to upgrade Mozilla Firefox, the following steps should help:

  1. Mozilla Firefox is now open.
  2. To get help, go to the burger menu and select Help.
  3. Select About Firefox from the drop-down menu.
  4. If Firefox isn’t up to date, the system will upgrade it to the most recent version.

You can also try running Firefox in Safe Mode, which disables all add-ons. This is how you do it:

  1. Launch Firefox.
  2. Then select Help from the burger menu.
  3. Select Restart with Add-ons Disabled from the menu.

5. Examine your antivirus and firewall software

Antivirus software that includes dedicated firewalls can be a valuable addition to security. On the other side, some of them are notorious for being overly tight and for prohibiting apps that should be restricted by default. That’s what you get when you do a task overly enthusiastically. To get beyond that (pun intended) wall, you can either temporarily disable the firewall (or permanently if you’re happy with Windows Firewall) or whitelist the VPN and Firefox.

Furthermore, under rare circumstances (particularly after security updates), Windows Firewall can act similarly to a third-party firewall. Even though most VPN solutions are allowed to communicate via the Windows-native firewall by default, there is always an exception.

If you’re not sure how to make a Windows Firewall exception, please follow the steps below:

  1. Type Firewall in the search bar and then select Allow an app via Windows Firewall.
  2. Click Modify the settings
  3. Allow another app is selected.
  4. Go to the VPN EXE file.
  5. Allow the VPN to communicate over both public and private networks by clicking Add.
  6. To confirm the changes, click OK.

6. Change your VPN server

To get the most out of a VPN, you’ll need reliable servers in various locations. The best-case situation is when they come as a set of numbers, allowing you to select the most appropriate one. You may need to swap servers occasionally, especially if one is down or running slowly.

The farther the distance between the client and the server, the higher the latency and the slower the connection. However, as previously said, the chance of servers failing or temporary unavailability exists.

To put it another way, the broken server may be working against you. As a result, make sure to try a few different servers and give it another shot.

Furthermore, as a side note, you can try changing the encryption protocols and seeing what happens.

7. Get rid of adware

Adware infestations and browser hijackers are both widespread nowadays. You might expect a slew of pop-ups or a change in your chosen search engine in the best-case scenario. In the worst-case scenario, your browser will stop working, and a more serious virus will propagate across your system.

When it comes to malware, it’s always better to be safe than sorry, so scanning your PC with a specific third-party solution is strongly recommended.

There are a lot of antivirus programs that offer browser security and Adware removal, but nothing does it better than Malwarebytes AdwCleaner for Adware and PUPs, in our opinion (Potentially Unwanted Programs).

The following are the steps to download and use this helpful tool:

  1. Malwarebytes AdwCleaner can be downloaded here.
  2. Start the program and select Scan.
  3. Remove anything suspect, even if it’s only a tad, and restart your computer.
  4. Restart Mozilla Firefox to see if the problem persists.

8. Reinstall Mozilla Firefox from scratch

Finally, if none of the preceding remedies successfully resolved your Firefox and VPN issues, you may always reinstall Mozilla and VPN from scratch. Although the latter shouldn’t make much of a difference, many users found that reinstalling Firefox helped them get rid of the problem. If you’re unsure how to execute a clean reinstallation of Mozilla Firefox, the following instructions should be helpful:

  1. Firefox should be closed.
  2. Type Control into the Windows Search bar to open the Control Panel.
  3. Select Uninstall software from the Category view.
  4. Remove Firefox from your computer.
  5. Go to the following locations and delete the Mozilla Firefox and Mozilla folders:
    • C: > Program Files > Mozilla Firefox or C: > Program Files (x86) > Mozilla Firefox
    • C: > Users > Your Username > AppData > Local > Mozilla
  6. Here’s where you can get the most recent version of Firefox.
