Firefox 113.0.1 Excessive memory usage & CPU Utilization at almost 90%+

[vmoutsop1]

Recent updates to Firefox has created a memory usage issue where memory in use goes from 200-400MB to 2-4GB opening 1, 2 or 3 YouTube tabs, plus protopage and a bugzilla page. Once the memory usage goes up, loading any web page tab goes from 0-5 seconds to 30-60-90 seconds or more to just load the page and then there is continuous stuttering due to massive memory usage.

I submitted an issue to Bugzilla but also started diagnosing extensions. It appears that the Malwarebytes extension is the culprit. I disabled all my extensions and re-enabled one by one and the problem started as soon as I enabled the MB extension.  I've done a factory reset but it doesn't seem to have much of an effect. I've had to disable the extension for now but it's not something I really want to do but I don't see any other way.

I use desktop and portable versions of FF and the issue exists on both installations. So, it is repeatable across installations.

Can you please try clicking on the Factory Reset and see if that helps?

Hi, as I stated in the original message: " I've done a factory reset but it doesn't seem to have much of an effect."

Please uninstall the MBG extension

Restart the computer

Then verify all is working well without it.

Then reinstall it and see if it has an issue still

If it does, then Download Debug Logs from support in the extension and post that back

Thank you @vmoutsop1

I had done this before, but when I tried it again, it seems to have worked. I didn't think it would, since it didn't the first time, but it seems like its working well now.

Thanks,
