Unfixable permissions issues
I can't launch Firefox on my M1 MacBook Air.
It says Profile couldn’t be created. Probably the chosen folder isn’t writable. The folder in question has a random name inside /Users/gisborne/Library/Application Support/Firefox/Profiles.
I've recursively set permissions on everything inside Profiles from the Finder. Didn't make a difference.
I also fairly often run into similar permissions problems in other apps. Those I can fix by manually setting the permissions in question, although quite often those permissions were fine the day before.
MacBook Air 11″, OS X 10.11
