For quite some time now I've noticed that I'm constantly having to re-log in on certain websites. Head-Case is fine, but for example if I don't go to Head-Fi for 2 days when I do go back I'm logged out. There are at least 4 or 5 other sites that have been giving me this grief lately. I'm on Firefox 3.0.5 on a Mac. I'm the only one on this machine so I'm not worried about someone getting on and pretending to be me. This problem is really starting to annoy me. Any suggestions? I do periodically clear out private data minus Cookies, Offline Website Data, and Saved Passwords.
