Ever since I've updated my Firefox for my mac, I can't open Binary files. Example: When I click on an email attachment a window opens - You have chosen to open "File Name" which is a: Binary File from: http:/where.ever Would you like to save this file? When I chose "save file" my "downloads" window would pop up but the file would not be there. I was able to remedy that problem to the point at which the file would show up in the "downloads" window but when I attempted to open the file I would get: ! Couldn't open the file. It may be corrupt or a file format that Preview doesn't recognize. So far this has happened with all Binary files I have attempted to open since my Firefox update. Never had this problem before. == This happened == Every time Firefox opened == I updated Firefox
