My home computer runs Ubuntu, and I use Chrome for the browser. Whenever I log in, close the tab, and navigate back to PF, I am logged out again. This doesn't happen on Firefox on windows or Chrome on windows. (haven't tested Firefox on Linux yet, I'll do that when I get home) This is despite having "Remember me" checked. Other websites keep me logged in just fine, and I haven't made any changes to my browser setup since it used to work. This only started happening within the past month or so.
