Forum and website • Re: Weird logouts

The forum errs on the side of caution and will log you out rather than letting a session continue if there is a failure of any of the checks performed. This can sometimes happen in case of a resubmission of your session ID from a different IP, for example, and the browser otherwise not presenting the correct markers. It may, in fact, be the forum protecting you from an active replay attack.

In case it is a matter of confusion, though, try explicitly logging out sessions by removing autologin keys in the UCP, logging out, clearing all cookies for forum.palemoon.org, then logging back in.
