Firefox does not launch on my Mac at all. After installing, everything was ok for a few days (I've installed some extensions like Disconnect, Adblock, ublock), and suddenly the browser stopped launching. I was trying to re-install it again but it did not work. Also, was trying to check hidden files and folders but nothing except some files in the MacOc content folder ( see att.). Could you please advise me on this issue hot to resolve it? Thank you in advance!
