Fix Facebook when it’s not working in Firefox

The simplest and the easiest way to fix Facebook when it’s not working in Firefox is to switch to a different browser. However, if Firefox is your default and favorite browser and you want to stick to that only, we will share some troubleshooting tips that will help resolve the issue.

1] Update Firefox

It may be possible that Firefox itself is causing issues if Facebook is not working on it. Update Firefox to the latest version. This will replace missing or corrupt program files, install bug fixes and the latest features to the browser, and improve compatibility issues with websites. To update Firefox, click on the menu icon (three horizontal bars) in the top right corner of the browser window. Then click on the Help menu and select About Firefox. A popup will appear as shown in the above screenshot. If an update is available, it will show the Restart to update Firefox option. Click on that option to install updates and relaunch Firefox.

Clearing your browser’s cookies, cache, and temporary data may help fix the issue. But before that, you must ensure that Facebook is allowed to use cookies and site data in Firefox. To check this, click on the menu icon. Then go to Settings > Privacy & Security > Cookies and Site Data. Then click on the Manage Exceptions button and make sure facebook.com is not listed there. Next, clear your browsing data following these steps:

3] Check your Firewall settings

Windows built-in firewall software may not allow Firefox to make connections. In such a case, Firefox will generate a ‘server not found’ error when you try to access Facebook. Configure Windows Firewall so that it will allow Firefox and Facebook to access your internet.

4] Check if JavaScript is being blocked

Facebook will not work properly if JavaScript is blocked in your browser. A browser extension or a firewall or antivirus software can block JavaScript. NoScript is one such Firefox extension that has reportedly blocked specific Facebook URLs after an update. Disable such extensions and then try accessing Facebook. A corporate firewall may also block JavaScript for certain websites that are not allowed in a work environment.

5] Refresh Firefox

The ‘Refresh’ feature removes third-party extensions, themes, and other customizations that may be conflicting with Facebook. It resets Firefox to its default state and creates an ‘old profile’ folder on your computer, which you can use as a backup to copy your old profile data (essential information such as bookmarks and passwords) to the new Firefox profile.
