I'm not exaggerating at all. I mean it crashes every 5 minutes. Without fail. I'm using the latest build of Firefox, 3.0, downloaded it on release day. It kept quitting without warning, so I reinstalled it. I've also uninstalled all my extensions except for Split Browser, AddBlock Plus and ReloadEvery, but there's no difference. Could one of those three be the problem? By the way, I'm on a Macbook Pro with OSX 10.4.11 Thanks!
