Facebook processor usage
When the facebook tab (home/news feed) is sitting idle & the current tab the processor max's at 100% in 24.2 (24.1 too). This does not happen in 17.0.11 nor does it happen in iCab's current version. It happens in safe mode. Can you reproduce this?

I can reproduce this exactly as you describe it. It's only on the news feed page (Home), which has a lot of auto-refreshing (Ticker), so I suspect something in this field. If you switch to another tab, processor load goes down immediately, and if you scroll on FB, load is high in any case, so you don't really notice the problem other than looking at Activity Monitor, but it's there. I've no idea what the browser is doing. Last version that doesn't show this behavior is 19.0.2.

Firefox 26 on macbook 32 bit intel core duo shows similar high processor usage where chrome shows no indication. Looks like its not just TFF!

This is probably DOM related, but as Phil points out, it is likely in cross-platform code.

Been around for some time as others have noticed it with no apparent solution.
