Authorization Problem - Memorization

So, it would seem a trifle, but annoying, the farther, the more:
The tick "remember me" when authorizing does not lead to any memorization. If tomorrow I come back to Habr, I will have to log in again. Moreover, today I read the news 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’s cookies also in some strange way spoils me a lot, there are now about 30 records mentioning it), but I’ve got enough of it. You click on the "favorites", for example, and you ignore. after updating the page you understand what you have already 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?
