+1. Sent my Firefox 16.0.2 browser into hyperspace on Ubuntu. Is there a way to just kill an offending tab? Pages like this take over my old-ish hardware so completely that trying to close a tab in the normal way is impossible. It is a design flaw for Firefox to allow any webpage to have this much power. Maybe a setting that forbids any page from consuming more than X% CPU for t time without explicit permission? Killing the whole FF process is far from ideal. I'd be willing to switch browsers if another better handled this issue?
