I can't believe no one could fix this problem in 5 (!) years, from Firefox 5 through 22 (= 17 major versions). http://apple.com -> images.apple.com cookie dialog hangs forever. re-starting FF does _not_ help. In other words, not possible to see Apple website in Firefox with custom cookie permissions. ----- { "application": { "name": "Firefox", "version": "22.0", "userAgent": "Mozilla/5.0 (Macintosh; Intel
