The slow startup isn't so much a problem for me, because I normally fire up firefox only once a day. However the latest 4.0 on Mac OS X suffer from a terrible memory leak, and I must restart it every two hours or less. else my mac slows to a crawl and restarting firefox literally takes minutes (swap...).
In fact it's so bad that I'll probably revert to FF3.6 on Mac OS X until there's a serious update.
