Latest Malwarebytes (4.1.0.56) give ransomware alter when I run Firefox 77

more options

I stupidly update firefox (76 > 77) and malwarebytes (see subject) on a single reboot. Went to run firefox and malwarebytes gives me a ransomware alert and closes firefox.

After some grumbling and other noises, I manged to get firefox running in safe mode and disables all add-ons. Firefox runs like a dream. Started to return add-ons one-by-one and soon had a list of issues (I gave up after five add-ons as it was just driving me mad to re-install firebox after malwarebytes quarantined it.

Of the five add-ons, three have caused the ransomware alert: Ghostery (alert), Start Page (OK), No Script (alert) OneNote (OK) and Save Page (alter).

Is anyone else having issues with the latest malwarebytes update?

I have submitted a support request to malwarebytes.

Thanks for that. Did the refresh, added back most of the add-ons (it was time for a culling anyway), moved profile and crash files to D drive from C drive. No ransomware alerts from Malwarebytes. All now appears good. It still may have been a rouge add-on but I don't intend to find out. Been surfing well for the last couple of hours.

Cheers

Yes, have completed this already. Have a ticket number, etc. Have advised malwarebytes support that it appears that add-ons are causing the issue.
