I have a problem with both Chrome and Firefox: they won't restore the tabs from a previous session after a restart. At first I thought there was something wrong with Chrome, since it's my primary browser, but now that I noticed that the same thing happens with Firefox, I think the problem can only be with OS X. Curiously, Chrome is able to restore the tabs from a previous session if it crashes; when I close it properly and restart the Mac, nothing happens. Am I missing something? I'm a Mac newbie, so go easy on me if the solution is obvious.
