Firefox not staying logged in to sites such as OCUK/Gmail

[CryptKeeper]

I've just reinstalled XP and whenever I use a site, such as ocuk, I click always stayed logged in. But when I close firefox and open it agian, I have to log in again. I have checked to make sure it is not deleting cookies upon closing, so thats no the issue. I can't figure it out. Anyone have any suggestions?

/edit solved this with some googling:

FYI,

Firefox 3 has an option to store third party cookies. There is also another option that says to only store them until Firefox is closed. It appears that when you install FF3 on a XP machine, the default installation checks this option. Uncheck that option, and the problem is solved.

The easiest solution is often the most likely one...

The default option is "Until they expire" here, on XP.

I did a fresh install of XP and updated everything (including IE), before I installed firefox. Perhaps that has something to do with it.
