Hello

Maybe, if you wish to test User Agent Switcher https://addons.mozilla.org/firefox/addon/uaswitcher

certain sites ( like FedEx tracking ) say that I can't visit because my browser needs an update. but I checked and Mozilla says that I AM up to date . last update April 28 What can I do to fix this?

The issue is you are using the old EOL Windows 7 as the most current version of Firefox you can run on Windows 7, 8, 8.1 is the older Firefox 115 ESR channel currently at Fx 115.35.1 and is based on the old Firefox 115.0 Release with security/stability fixes since. The last planned update will be Fx 115.39.0esr in August unless Mozilla decides to extend updates yet again.

To be able to run Firefox 116.0 and later including the current Firefox 150.0.1 release and 140.10.1esr you need Windows 10, 11 or macOS 10.15 or later or Linux.

A working environment (user) in a given situation does not correspond to a working environment (other user) in a given situation, please understand that it is difficult to give an opinion.

On Windows7 Firefox 115.35.1esr, i tested a page fedex tracking, i can't reproduce your dysfunction.
