I think I may have gotten a bug from a add-on that you could install, because I can't open my cookies menu anymore and has infected my computer

I was just trying to find a way to get a video off the internet so I searched it up and found a video for a specific add on that was on Mozilla Firefox, so I downloaded it, and soon after I got it my browser wouldn't let me open my cookies menu anymore. And i'm afraid it infected my computer too, because now I can't open my Control Panel Application on my windows computer anymore. The Add on is called "Flash Video Downloader- Youtube HD Download [4K] 6.9.3".

It is possible that this extension isn't fully compatible with the current release and is causing this problem.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

  • Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
  • Do NOT click the Reset button on the Safe Mode start window
