After installing Waterfox 64 bits the log in on several forums won't work. Account or key won't be stored. Impossible to log in. Google Chrome however works fine on the same sites. Am using Waterfox because I like to use the Photobucket uploader. Chrome doesn't have that option. Removed Adblock but no result. Found out that Nightly, a 64 bits equivalent of Waterfox is working correct. Also the 32 bits Firefox shows the same problems as the 64 bits version.
