At some point over the past few weeks (maybe even months), for any Baseops page I open, the top tab continues to spin as if the page is still trying to load. The page is fully functional, but it's as if it's still trying to load up. It only happens with Baseops (forums and main pages), no other pages. It only happens with Mozilla (29.0), I'm using Windows 7.

I've looked at the Mozilla FAQs and nothing seems to fit (it addresses the spinning, but only for websites that don't open or completely lock up).

Do you have some kind of ad-blocker running? I've seen various sites on various browsers behave the way you describe when the ad(s) can't phone home with your IP--the page appears normal (all the stuff you actually want to see is in place), but the browser sees something still trying to load....
