    what the hell happened this beta is 3 times slower than ff8

    I find it probably one and a half times quicker than FF8.

    If you are using lots of add-ons, restart the browser with add-ons disabled and see how you go. Go through the add-ons and enable them one at a time so they are the only add-on that’s running. This should quickly enable you to see if any of them are causing the slow down.

    Otherwise I would recommend posting at forums.mozillazine.org and asking for advice.

    If you want help then you need to post more detail about your system, add-ons rather than just saying it’s slow. If  however you’re just doing some light trolling, then good luck to you.
