All of a sudden firefox starts to lag,tried refreshing it and re-installing it,nothing seemed to work Especially on Gmail and youtube(haven't tested other sites,cause of slowness)even firefox's option page also starts to lag. Scanned my pc for viruses and updated my windows,uninstalled my addons,tried every step i can search of. Version : 79.0 addon: Mcafee web advisor setting changed: None(both pc's and browsers) is it a problem with the firefox or mine? Thank you for taking the time to read this Have a nice day
