So, because of one poorly designed shitty website you're moaning about FF being bad? You should be moaning about Twitter with its bliveted 8 tons of javascript in a 5 pount sack.
You can add espn.com, washingtonpost.com and nytimes.com to that list as well.
I'd rather a browser that can handle shitty websites than hoping every website will somehow magically be written efficiently. Especially since FF is the only browser I know of that can't handle multiple active javascript sessions. It's completely absurd if you think about it, I mean it's a browser, for browsing websites, which use javascript.
You can add espn.com, washingtonpost.com and nytimes.com to that list as well.
Blivetware.
