Suddenly getting persistent "Gah. Your tab just crashed" error message this week; running Windows 11 on a Lenovo X1 Carbon 12th Gen laptop; I have run Firefox in Safe mode, disbled multi-process tabs, turned off h'ware acceleration, cleared cache and cookies, turned off BitDefender, Refresed firefox, updated firefox and windows, checked for malware, reinstalled Firefox, and attempted to create a new Firefox proficle (didn't run), all to no avail; attempted to use mozregression, but I don't have the skills. Would be glad of any help! Thanks
