A couple issues I see. 1) Completely removing the functionality for Opera, Safari, and FF 3 seems like a bad idea - we like to make sure that everything is cleaned up after we're done. 2) Is there some alternative event that we should be binding to for Opera in order to clean up our event bindings? 3) Is there a way to detect that binding in a way that doesn't involve browser sniffing? 4) It sounds like this might be a bug in Firefox 2 and Opera - if they are incapable of maintaining the cache when an unload event is bound. Presumably this was fixed in Firefox 3?
