I am using Firefox 50.0 on OSX El Capitan. I was experiencing the same issue on 49, so I upgraded to 50 beta to see if it would help, but it does not. Every time that I start Firefox, I get a notification to update to the latest version, even though I am on the latest version. If I select "Restart Firefox" from the notification, Firefox restarts and shows the notification again. When I choose "Restart Later" I can browse normally.
I was trying to get help on this thread started by someone else (https://support.mozilla.org/en-US/questions/1141443), but no solution was found.
I do have a clue that may help. I use 2 user accounts on OSX, one for work and one for home. I'll refer to these as accounts A and B. OSX account B was the first to show the problem, running Firefox 49. I followed instructions here (http://osxdaily.com/2014/07/31/manual-complete-app-removal-mac-os-x-terminal/) to use mdfind to remove firefox files, but that did not seem to help. Finally, with account B, I upgraded to Firefox 50 and stopped getting the notifications. However, now I get the notification in account A. In account A, Firefox reports as version 50.0, but still asks to update.
I imagine that there is something OSX account specific causing problems, but I don't know what that might be. Any help is appreciated.
