I can't seem to be able to apply the latest update of Firefox. It got downloaded and it's updating but won't finish the process. My computer even crashed during it and said "your computer was shot down because of a problem." It restarted itself and when I go back and click on About Firefox it still says "Applying update." How do I fix this problem? I'm on iOS Catalina 10.15.7 /edit: moved thread from Firefox for iOS (for iPhone/iPad) to Firefox section as you have <b>macOS</b>.
