New Mozilla Firefox 3.0b5

I was having some problems with Mozilla Firefox lately. My pet guru suggest that I upgrade to the new Beta Firefox. I have to say that it seems to make my four year old notebook quite a bit faster.
My pet guru recommended that I uninstall the old Firefox first and save it in the same folder. To do that you chose the custom install option and when it recommends where to save it you remove the 3.0 and Beta information.
I did this and seem to have NOT lost any bookmarks, saved passwords or anything. However no promises, you’re on your own.
