Had to disable Browser Guard because of problems with far too many websites that I access on a frequent basis (MS Edge works fine). Problems noted:

  • Slow loading of many website page.
  • Firefox often hangs up (cannot close webpage) when loading websites.
  • Problem most severe when load a folder of websites at the same time.
  • After Firefox hangs up and I try to open Firefox again, get error message that Firefox is still running.
  • All sites with problems are configured in Firefox settings as "allowed" safe sites.
  • Latest update didn't resolve the problem.
  • Microsoft Edge works smoothly.
  • Reimaged PC to Windows Image saved a month ago to see if older version of Firefox would work better--No improvement, problems noted above persist.
  • After disabling Browser Guard, Firefox was able to quickly load the same sites I was having problems with, even when opening from a folder of multiple sites.

This problem is a recent development, what changed? -- Are Browser Guard updates different than Firefox browser updates?

Note that with 111, you are a few versions behind as current is 113.0.1.


Browser Guard is a third-party application and not part of Firefox, so in case of issues best is to contact its creator (Malwarebytes) for support.
