Firefox will not keep me logged in to any site

Hi,

Now i'm getting tired from firefox. Whenever I sign into any site I always check "keep me signed in" or something always to remember my password by firefox . But as close the firefox, it forgets the last login and always i have to re-login again. How can i fix this problem? I wasn't facing with previous version , since i upgraded to latest one by automatic update i'm facing this problem .

Please help, thanks in advance.

Some sites set a cookie for longer logins - I believe Yahoo does that if you tell it to keep you signed in. If you have cookies disabled you don't get the cookie, so you're logged out after some fixed number of minutes of inactivity.

For other possible causes, first try clearing the cookies for the site, there may be a malformed cookie causing the problem. In the Firefox menus select Tools > Options > Privacy - In the Cookies section click "Show Cookies..." to access the option for removing cookies.

Also make sure that cookies are being accepted and not being deleted when Firefox closes. Go to Tools > Options > Privacy, on that dialog you can make sure that cookies are being accepted, then in the private data section make sure that Firefox is not set to delete cookies when Firefox closes. Also click on the Exceptions button in the cookies section to make sure cookies from those sites are not being blocked.

Tools > Options > Privacy > and uncheck the check box that says "Always clear my private data when I close Firefox"

Restart Firefox and login to your sites.
