hi dsly, please try to press Command-Option-K in order to open the firefox web console, and click on the settings icon on the top left. in this panel tick the option to "disable javascript", which in turn should make it possible to leave the malicious page immediately...

Philipp Thank you for your reply. I will try this solution the next time I have a hostile take-over!

It says 'current session only, reloads the page'. Does this mean it will restart the 'vicious circle' all over again? Dan

no, this doesn't start a circle - once you leave the site with js disabled it will be gone for good...

I was surfing the web, when somehow I landed on a bad web site. The web page displayed a so-called message from the FBI (you know the one), and Firefox was locked. I shut down FF via the Windows Task Manager. When I tried to restart FF, FBI was back. I shut FF down. Then, using the Open New Window option, I was able to get FF up.

This add-on can stop such pages; disallow Script Button {web link} The Disallow Script button looks like a letter "M" and the title is the Minus Script, drag and drop the button on a toolbar. If the button is not displayed then nothing operates, except rules for plugins.

You can set the Integer pref browser.sessionstore.max_resumed_crashes to 0 on the about:config page to get the about:sessionrestore page immediately with the first start after a crash has occurred or the Task Manager was used to close Firefox.
