3. Disable Extensions like Ad Blocker and VPN

The extensions can cause you problem after Firefox upgrade automatically to the latest version. In our experience, especially ad blocking and VPN extensions cause unintended results and crash the browser. If you have ad blocker or similar filtering extensions, disable them and check it helps.

It is also good idea to completely disable all the extensions or use private mode to check the browser. You can go to “about:addons” page and ensure the browser does not have any installed extensions before you check.

5. Remove Proxy Settings

The advantage of Firefox is that it has an inbuilt proxy setup to route the internet connection. This helps you to have two network setup – one for Firefox and other for your computer. Unfortunately, the custom proxy setup can also cause some trouble to the browser.

  • Click on the “Settings” button against under “Network Settings” section.
  • This will open the “Connection Settings” pop-up.
