Running 3.6.8 currently and about to upgrade but also about to move servers so moving server first then upgrading.

Problem is this - Site is located at www.talkangling.co.uk/upload

I have ticked the "remember me" so should be automatically logged in.

When I go to the site in IE7 everything is fine.

When I go to the site in Firefox the shoutbox doesnt come up and I dont appear as logged in, as soon as I click on a thread or forum I am then logged in... so seems strange. Is it something I have done wrong?
