Firefox updated to 142.0 - now my bookmarked websites not working - Apple tech had me delete all my Firefox cookies to determine that it was the 142 update from yesterday that caused the problems because I can access my bookmarked websites using Safari
Yesterday (8/19/2025) I updated to Firefox v. 142 from v. 141.0.3. The Firefox update was the last thing I did prior to shutting down my computer. Today, when I booted up with version 142.0 many of my bookmarked websites don't work. I am using a iMac Retina 5k, 27-inch, late 2015 desktop computer using macOS Monterey v. 12.7.6
I called Apple tech department & explained my problem (see above). He had me delete the cookies for Firefox to see if that would correct the problems. It did NOT resolve the problems. He had me switch to Safari browser to see if I could the access the websites with which I was unable to access. I was able to do so. He stated that the problem was with Firefox and that he could NOT help me any further.
I have NOT used Safari for a decade or more and am NOT familiar with it because I found Firefox to be much better and easier to use. Until yesterday, I had NO problems. Now I am desperate to be able to continue to use Firefox but can't access important sites that had been available until the 142 upgrade. HELP, PLEASE
