When I log in the forums, After sometime it doesn't remember me and logs out even though I checked remember me.
Is this a cookies problem?

if you uses annonymous mode on you browser,doesnt work.

I dont use anonymous mode in my browser because why should i?

I use firefox.

I Did remember me but how do i enable the cookies?

thats strange.
The cookies are accepted and everything is okay but what about keep until option, seems suspicious to me.
the keep until option got "keep until:They Expire or until I close my browser"
does this have any relation to my situation?

Tools > Options > Security > Check the box "Remember logins for sites"
Then, log with your toribash account.
Go to the options, and click "Saved Logins" to see if your login was saved.

Life , what you said is on and no problem but nothing is making a difference.
you too pimp it didn't work, either.

ok, Any other solution?

uhm, do you use any cleaning software a lot?
Also check at option if u always remember history activated
