Dear Friends, For almost a month now I am unable to use Firefox - on startup it crashes giving the error message '''"Gah. Your tab has just crashed"''' I have tried every method/suggestions I found on the net. As per my Norton 360 & Malwarebytes Antimalware my m/c seems to be clean. Also from Help if I try to restart Firefox in Troubleshoot mode, it closes but never start up on its own. It needs to be manually started. Also in about:support page the about:plugins link doesn't work. Any help will be highly appreciated. I am attaching a screenshot of the error message. I am using version 88.0.1
