Problem with authorization - remembering

So, it would seem a trifle, but annoying, the farther, the more: The
checkbox “remember me” during authorization does not lead to any remembering. If I go to Habr again tomorrow, I will have to log in again. Moreover, I’ve been reading the news today for an hour (or so) and I just had to log in, because Habr "forgot" me.

I don’t know how it should work, cookies or something else (by the way, Habr also spoils a lot in some strange way for me, there are now about 30 entries with its mention), but it’s rather crippling. You click on “favorites”, for example, and you are ignored. after updating the page, you understand that you have already been thrown out. Yes, and just log in every day, and several times a day ...

Maybe I'm doing something wrong?
browser - FireFox 1.5.0.1, Java enabled, cookies too. Where is the crap?
