Lately Malwarebytes is flagging firefox files for quarantine. I get messages like these daily now when I never saw any in the past many years of using Firefox and Malwarebytes.

The PREFS.JS file contains user options and settings.

Something in the file is causing the problem. Do the error messages say anything else?


Use these links to create a new profile. Use this new profile as is. Is the problem still there?

what you see above is exactly what MBAM reports which I am able to save to a TXT file. This is what I received on Saturday:

You will have to contact Malwarebytes for support if you have a question about their software. Like posted above, prefs.js only contains custom settings and shouldn't be a threat (i.e. it is a data file and not an active file).

Note that usually best is to exclude the Firefox profile folder from scanning by security software as this only gives issues and can lead to data loss or data corruption.
