Javascript user interface script timeouts

While working with Zimbra today on a fairly loaded machine, the user interface was timing out for me in Firefox. Basically every 5 seconds or so I would get a warning that said "this script is making firefox run slowly, press cancel to stop it".

Now, I have quite a few messages in my inbox, so I dont really fault Zimbra for taking more than a couple of seconds to deal with it, so I went looking for a way to disable this warning. I documented it in a Firefox Script timeouts wiki entry in the RoWiki
