I've found a way to make Firefox painfully die: it stops responding to the most of clicks, but the window is not frozen. You just can't click any button or close the page or close firefox: it's process stays alive even when it's window gets closed.
STR:
1. NoScript -> Options -> Advanced -> Untrusted -> Forbid META redirections inside <NOSCRIPT> elements.
2. about:config -> network.http.redirection-limit -> 0
3. visit http://vk.com/leprum
Then you either get the bug instantly or have to click some links a few times. When you see a page that says you need js+cookies to be enabled to view that site and suggest to pick firefox/opera/chrome - that's it, the browser now is dead.
Actual result: Firefox dies painfully.
Expected result: it should work fine.
