These problems have reappeared with Firefox 93. Last night I tried to fix it (which I mentioned in another thread) by Refreshing Firefox and initially it seemed to work (although I don’t recall trying Tidbits). The only changes I made to my profile afterwards were to restore the search box at the right of the address bar, to restore Google News as my Home page, and to adjust Firefox Synch to only cover bookmarks, passwords and history. Yet when I try to go to Tidbits, Firefox simply does not respond. If I enter Tidbits in the address bar and press ENTER, it restores the address of the page it was on before. I have not restored AdBlockPro, which I had suspected of causing problems. I quit and restarted Firefox. Still no Tidbits.
The only things I have not tried are restarting the Mac and signing out of Tidbits, which I can access on Safari. I suppose it’s possible there is some access problem. When I tried Traceroute in Network Utility, it warns me:
Warning: tidbits.com has multiple addresses; using 188.8.131.52
traceroute to tidbits.com (184.108.40.206), but does make a connection.
Tidbits is not the only site I have been unable to reach with Firefox, but I have not kept track.
Any ideas? I’m going to try restarting next, but am sending this first to document the issue.
