Apparently randomly, about every 2-7 days, all my extensions become disabled with no option to enable them again. I delete the compatibility.ini and all extensions.* files and the extensions are then enabled again. I have tried creating new profiles, but it keeps happening. I have scanned for viruses. I have the latest versions of the extensions. I sometimes *need* to run Firefox ESR v52.8.1 (64-bit) in parallel. I wonder if that could be the cause..? Firefox v. 78.0.2 (64-bit) OS WIN7 (64 bit)
