User Agent: Mozilla/5.0 (Windows NT 6.0; rv:11.0) Gecko/20100101 Firefox/11.0 Build ID: 20120312181643 Steps to reproduce: When a particulary laggy URL is opened (such as a PDF file) to the extent that it crashes the browser, and the browser is shut down by the user with CTRL-ALT-DEL - and the browser is re-launched - the browser naturally tries to re-load all of the previously opened tabs. This wouldn't be a problem, except that it re-loads the malicious/laggy URL that just crashed the browser!
Most errors happen during the first few seconds, and these urls are not (yet) saved in the sessionstore, so you don't see the problem. If such an malicious tab is loaded anyway, you can indeed crash when loading all tabs again. But the second time this is detected, and you get a list of all tabs that would be restored. You then have the opportunity to load all tabs, except that one that causes the problem.
