I don't think I'm willing to compromise my add-ons and extentions... it's the only thing that makes FF worthwhile. I cleared my cache and it's still lagging. I finally went back to 3.6 and things are back to normal again, finally. I would rather use IE than ever going back to FF4.
Downloaded FireFox 4 and like it so far. I think it is loading faster than 3.6 for me. I don't have a ton of extensions, just a Theme, and WebDeveloper Toolbar and Firebug. They all work with FF4.
