Firefox tabs falsely detected as "Not Responding"

[OpenSource Ghost]

Windows 10 19045 detects many opened Firefox tabs as "Not Responding" and using "Kill Not Responding Tasks" (taskkill.exe /F /FI "status eq NOT RESPONDING") command crashes those tabs, but those tabs work fine and respond perfectly unless that command is issued. I do need to use that command for other tasks, but not Firefox. What can I do? How can I prevent WIndows from detecting Firefox tabs are "Not Responding" ?

I don't have that issue with Firefox on Win10. Maybe uninstall Firefox and reinstall?
