You can use it to go online and surf the web and, with the help of add-ons, carry out various functions and tasks. Sometimes it happens that something suddenly no longer works or Mozilla Firefox no longer works at all.

When Firefox doesn't work anymore

There was probably a new update from Mozilla or your operating system. Perhaps you have installed a new add-on or new software that introduced an add-on. Anything can lead to conflicts in the systems and paralyze Firefox.

  1. First restart your PC and open Firefox. Under the menu item "Help" you can click on "Restart with deactivated add-ons".
  2. Confirm the action and the browser will restart once without any add-ons present. Test to see if he goes now. If so, the best thing to do is to reactivate one add-on at a time and see which one may have been the trigger.
