I can not update Firefox because my computer is MacPro Version 10.11.6. My computer will not accept new versions of its operating system. And your Firefox updates will not work on my version. So I am using 78.15.0esr . I do not know what to do - since I can not afford nor do I want to replace my MAC. All my important software is on it. All my important documents are on it. And it works beautifully.

I will have to continue to use Firefox 78.15.0esr . Can you suggest any alternatives for me?

I have the last Firefox version and am trying to add extensions (e.g. video download helper). When I click on Add to Firefox, it works at loading the extension, but without any success. The blue dot in the gray square dances and dances and dances.... Thanks !!

I have a user at my job that installed the latest Firefox update (13324.11.21) through our MDM. After installing this update she cannot launch Firefox. When attempting to launch she receives a request for a username and password to install a Helper Tool. She is an admin on her machine and enters her credentials. The message closes and nothing happens. When attempting to launch again the same thing happens. This is not happening with our other 100 Macs who have the same Firefox version and others who have the same OS.

Is anyone able to tell me why this is happening or how to fix? Any assistance is very much appreciated.

The below troubleshooting steps have been done:

Uninstalled and reinstalled Firefox

Updated the OS to 15.0.1

Disabled the Master Password on Firefox through a Mac Profile

Checked if there was a Firefox file under /Library/PrivlegedHelperTools

Granted Full Disk Access to Firefox under System Settings
