When I go to websites i.e. PayPal, Facebook, eBay, amazon, etc I get emails saying that I used an unknown browser that I have not used before. This started with your new update 90.0.2 64 bit. I am not technically savvy what do I do to stop these emails and let them know it is fire fox mozilla browser. Fire fox is my main browser and has been for years but, unless there is some way to let websites know this is a new update to fire fox Mozilla I will be forced to remove this browser from my computer. Please advise me what I can do. Thank you. Katisam3@cox.net

Hi Katisam3,

Try opening firefox in Safe mode,

  • Find the Firefox icon or click Start and type Firefox.
  • Hold down the Shift key on the keyboard and then click the Firefox icon.
  • In the Firefox Safe Mode window, click the Start in Safe Mode option.

Safe Mode is a troubleshooting mode that temporarily turns off hardware acceleration, resets some settings, and disables add-ons (extensions and themes), any userChrome.css/userContent.css files, and some other advanced features to help you assess whether these are causing the problem. If the problem goes away, that tells us one thing. If it does not, that tells us something else.
