Oh, and here's something else:
Lately, most eBay pages continue "loading" non-stop for me. They only stop when I click the Stop button or navigate to another page. The page actually finishes loading -- as far as I can see -- but it's obviously still doing something.
In Firefox I keep noticing that animated "loading" icon in the tab and it drives me nuts.
Does this sound symptomatic of anything you folks are aware of?
