Ever since the update, I cannot open Firefox at all. I'm currently on a Macbook Pro 13 inch / 2014 running Mojave 10.14.6 (on purpose. I despise Catalina). Since yesterday, I've tried: - opening in Safe Mode - two clean installs - checking profiles - running maintenance with Onyx (cleaned caches, etc.) - running Malwarebytes (no flags) . . . and nothing is happening. I went through the same thing with the Firefox version just before 74 and never found a resolution to it. (I wasn't bothered much as I was spending more time on other devices that had Firefox installed and working.) But now I'm back to my reg. computer. Firefox is my absolute all-time favorite browser (created by my absolute favorite folks: Mozilla!), and I'd really like to be able to use your wondrous software. Any and all help would be appreciated. Best— CM PS: I'll go ahead and reset the PRAM to see if that helps, but I'm not seeing anything that looks like kernel panic, so. . . ?
