Hmm In your More system details on right the UserAgent you used to post this thread with is Mozilla/5.0 (Macintosh; Intel '''Mac OS X 10.10'''; rv:78.0) Gecko/20100101 Firefox/78.0 It appears you are using the rather old macOS 10.10 ? If so then the most current Firefox you can run on macOS 10.9, 10.10, 10.11 is Firefox 78.15.0esr https://support.mozilla.org/en-US/kb/firefox-mac-osx-users-esr Firefox 79.0 to 115.0esr requires macOS 10.12, 10.13, 10.14 at minimum to run while Firefox 116.0 and later requires macOS 10.15 (ten.fifteen) at minimum to run. I moved this thread from Firefox for iOS (for iPhone/iPad) to Firefox section as you have '''macOS'''.
