Could Avast be Keep Firefox Remembering Login Credentials?

I’m using the latest Avast Free and the latest Firefox version and sometime recently Firefox quit remembering login credentials for websites doesn’t matter which one despite being checked to do so. Firefox has always been checked to remember website logins and no issues in the past.

Something has changed… was wondering if Avast could be responsible or more likely Firefox?

Hi, I’m not aware of any issues regarding FF.
