It started when using the chat of Facebook but after also when playing it's games, that this screen "Unresponsive script" pops up constantly and the browser freezes till I click on the markers "Don't ask me again" and "Stop script" This started to happen when I updated Firefox because this never happened before. I loved Firefox but now it has become very annoying.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

  • Don't make any changes on the Safe mode start window.
