Firefox Support Forum

Had a sign that I needed to update so I clicked update and it did not complete. I clicked Close Firefox and got XULRunner Error: Platform version '101.1' is not compatible with minVersion >=101.0 Max version <=101.0’ for ‘Firefox’ and can't,t get past it. I've updated for years and nothing like this has happened before. Do I need to uninstall and reinstall? if I do will I lose all my bookmarks and saved pages? Any other workarounds???

I was trying to customize the toolbar and I can't recall how, but I lost access to my extension shortcuts through the menu list button on the toolbar. I've been since trying to get the button back or replace it, to access my extensions that way but I'm not finding any options to get the button back which I find ridiculous because the button is very helpful on the toolbar in utilizing your extensions. I'm kind of a newbie so I'm looking for help in how to get the button back on my toolbar so I can utilize my extensions that way, please. Thanks.

There was an upgrade to fire fox yesterday and now every thing is huge. I can hardly see my face book page and I have spent over 2 hours trying to get it back to normal size. I have windows 10.

Firefox on Windows keeps telling me that my tab has crashed every time i open a new tab. I have tried turning off all my extensions and add-ons, clearing the cache and cookies, turning off hardware acceleration, reinstalling the browser, clearing the appdata files and finally removing any and all firefox files in mozilla folders i could find on my computer, but nothing works. Strangely enough it works only when i open it in troubleshooting mode, even though I've reinstalled the browser 4 times now. It was working just fine earlier, but when i turned on my computer it would not work. The only thing i did in between it working and not working was play a videogame on Steam. Please help, this is driving me crazy. I am using an MSI 64-bit laptop and the latest version of Firefox 64-bit.
