Firefox installed in Windows 10 (64). Just recently FF will not open when executed even though Windows Task Manager shows it is a running process. I've rebooted and reinstalled to no avail. It's the latest version. Any suggestions?

Could this be relevant? A couple of other users identified Webroot (security software) as blocking 64-bit Firefox 97 -- released today -- from running properly: If you are still running an earlier release of Firefox, this would not be your issue.

In case you do use Webroot.
