 Your problem is that Firefox is anticipating the users movements, and
 automatically loading the adjacent post into memory/cache, in doing so,
 it'll set any cookies which that page returns.

 Ideally, any cookies with per-page information should be prefixed with the
 post ID, and/or better suited to be printed as inline javascript in the
 footer/headers.. doing it that way will not cause you problems.

 However, this is not a WordPress bug, it's just the way your PHP interacts
 with a browser, it's not something that WordPress can 'fix', nor affect..
 (Other than not including the adjacent posts links), It'll happen with
 *any* php/application which firefox interacts with which doesn't use
 unique cookie names.

 Closing as invalid due to that..
