Last Friday I took up the firefox update. I always wait 3 days b4 I do in case there are any bugs. Lost everything on desktop and there was a msg " This update is not compatible with yr computer, please re-instal firefox" but it was a catch 22 situation cos every time I tried to re-install firefox I got nothing but the same message! I had version 133.0 (64 BIT) and the newer version was & still is 133.0.3. Eventually Edge came to my rescue and took me back to the older version (133.0). Then a couple of days later I'm getting incessant offers to update! I checked the Firefox updater & the new update is the same as the one that caused my desktop computer to crash so keep dismissing it unless u can promise me it wont happen again! My son is an IT specialist; he had to drive 100 miles to come help me get back everythng I lost. I dont like the newer update .. not interested in side bars; just want it to be the same all the time! So question is: if I take up the newer update, is it still incompatible with my comp? Am running W10 on it.
