Just as was reported [https://support.mozilla.org/en-US/questions/1313461] here, when I went to Google today, none of the famous "People also ask" dropdowns would work. Neither would any of Google's custom javascript widglets (I made that term up. They are likely Angular apps). This behavior also happened with some of the controls on my online bank's pages. This behavior is not present in Edge. This is a new computer to me, and once recently, I lost control of some of Firefox's own menu items (I could scroll to items on the 3-bar menu, but not click some of them). Don't know if the two problems are related. The only thing that fixed that issue was to re-install Firefox. I'm currently on Win 10, FF 94.0 (64 bit). I have tried all the standard advice: clearing cookies and cache, starting in troubleshooting mode, refreshing Firefox, and fiddling with performance settings (am I right that turning on and off hardware acceleration is no longer an option?). Since I did try troubleshooting mode, I don't think this is caused by an extension, but who knows...is it possible for an extension to break FF, then have the broken behavior continue even after refresh? I'd really like to figure this out so I don't have to re-install the program every time this occurs. Thanks for any help! -Josh
