As far as email sites go. The "Adblock Plus" extension with at least the "EasyList US" filter subscription would probably help. I does block a lot of unnecessary Script files whose sole purpose is to provide advertising. You can of course add additional filter subscriptions or filters of your own. There are many extensions that can cause such problems, and you may have to go through your extensions. One thing you might do is eliminate Problematic Extensions that you are not using, but mainly check to see how the create problems and you may have to make a choice between extensions. The Unresponsive Script Warning page lists some extensions with problems (thought it listed more) and describes how to check through your extensions to help find which extension is the problem Sometimes the message will tell you. * '''Problematic extensions''' - MozillaZine Knowledge Base<br>http://kb.mozillazine.org/Problematic_extensions * '''Unresponsive Script Warning''' - MozillaZine Knowledge Base<br>http://kb.mozillazine.org/Unresponsive_Script_Warning * Firefox hangs - MozillaZine Knowledge Base<br>http://kb.mozillazine.org/Firefox_hangs Here are some extensions I had a problem with, and don't use them any more : http://dmcritchie.mvps.org/firefox/infolister_listing_fx4.htm#scriptbusy * Line Marker, Firefox 1.0 - 1.5.0.* ALL (2.0.2006072201) * Quick Sum (0.1), presumably good for Firefox 2.0 * Translate (0.6.0.9), Firefox 0.9 - 1.5.0.* ALL * gTranslate (0.3.1) [30KB], Firefox 1.0 - 2.0.0.* ALL <br><small>Please mark "Solved" one answer that will best help others with a similar problem -- hope this was it, but take your time and try to make sure you pick the answer that helped you, and tell us which extension or script you found to be the problem.</small>
