This an annoying problem I'd like to sort out. On my laptop Firefox won't remember my username / password on WebmasterWorld for example. I have to click on login and my details appear there rather than being remembered and logged in automatically. This happens on all sites where a cookie's set for automatic login. I'm now on 3.5.3 but this has been happening in previous versions. I've tried deleting cookies etc but no dice - any suggestions?
