Firefox is a fantastic web browser and has many features that make it an excellent choice for users. However, like any browser, it is not without its issues. Recently, a bug has affected large numbers of Firefox users causing their tabs to stop loading. Luckily, Mozilla believes the issue has been fixed and restarting your browser should restore normal functionality. In the meantime, there are several workarounds you can try to help resolve this problem.
One of the first things you should do when Firefox tabs won’t load is to ensure that your network connection is up and running. You can do this by connecting to a different WiFi network or trying a wired Ethernet connection. If the issue persists, you can also try resetting your Firefox preferences to default. This will reset the settings of your web browser but will keep your passwords, bookmarks and cookies.
Another common cause of Firefox tabs not loading is outdated themes or extensions that are causing conflicts with the web browser. You can test this by starting Firefox in Safe Mode which will disable any hardware acceleration or extensions and change the theme to the default. If Firefox loads pages normally in Safe Mode, you can start troubleshooting by following the steps outlined in our Troubleshoot Extensions, Themes and Hardware Acceleration Issues in Firefox article.
You can also try disabling any plugins that you are using on a site by clicking the three horizontal lines in the top right corner of your web browser and select Add-ons. From here you can disable any plugins that are causing issues by toggling them off.
