Firefox and Firefox Developer Edition suddenly won't start anymore [MAC]
Dear,
A little time ago i've installed Firefox Developer Edtion for CSS tweaking (my Firefox was already installed) They BOTH worked on several macs (very rarely besides started both) for quit a while.
Suddenly, they both wont start Anymore: Your Firefox profile cannot be loaded. It may be missing or inaccessible (only by Terminal, but after create new profile didn't help)
- The Firefox profile manager is too old and dated 2015, also has a massive screen position bug - Removing 1 Ini (other could not be find) didn't help - Removing App Support Mozilla and Firefox folder and Rebot mac didn't help - Starting with Shift; no profile, create new profile OK - after reboot Firefox same error - Reinstall did'nt help
Could please help me out..??

For now...... i did solve it myself by completely de-install ALL Firefox versions with MacBooster, then Reinstall them again. For now i only use Firefox Developer

It sounds that there is a problem with the profiles.ini file and that you aren't able to save changes to this file. Try this to see if you can repair the file system.
