FF doesn't load any pages anymore except for mozilla's own pages

I am using FF 64 bit, latest version (91), on Win8.1. Out of nowhere, FF has ceased to load any pages but mozilla's own pages like the help page I'm writing on. I've no themes installed and 2 windows open with approx. 155 tabs. I've tried turning of hardware acceleration, checked for proxies, updated FF, restarted FF, checked the Windows firewall (all permissions granted) and avast antivirus (ditto), checked for malware with avast antivirus - but all to no avail.

I am at a loss with this problem and kindly ask for advice. Januario

Thanks for your suggestions. After going to PROFILES, I tried to restart with all extensions disabled and - lo and behold, FF resumed working properly. Then it was easy to find the culprit. I tried several extensions until I disabled umatrix. I was on 1.4.0. That old one did not dovetail with FF91. But 1.4.4 (the latest version) did the trick.
