Last Tuesday, Win 11 AND Firefox both updated on the same day, Firefox to 113.0.1. Ever since, my Firefox has experienced SIGNIFICANT lag time loading even the most basic of websites. It feels like Netscape 1.0 slow (yes, I'm that old). I've disabled 2/3ds of my addons to see if that would help and it hasn't. I don't know if it's an issue with the Win 11 update (KB5026372), with Firefox or some combination of both, but any help in addressing this issue would be greatly appreciated.

Your System Details shows the Malwarebytes Browser Guard extention. We have seen reports from Firefox 113 users that Malwarebytes Browser Guard is causing slowness issues, so if you use this extension best is to contact its Malwarebytes for support.

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.

  • switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes
  • do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window

Mr. Cor-El.... THANK YOU SO MUCH for taking the time to reply to my desperate plea for help. You nailed the issue right on the head. My system is back to running full speed again.

I use Malwarebytes in addition to a couple other addons (including Privacy Badger) so I'm not overly concerned about disabling it until I can get a solution from Malwarebytes themselves.

Your time and consideration is most gratefully appreciated.  :-)
