btw if you like to try betas or have several versions of FF using the same profile, I found out how to get rid of that "thank you for trying" page on first start after switching versions. After awhile it can get pretty annoying.
This info should be enough to get you there:
==================================================
To get rid of the "Welcome" in FF 3.x in the address bar type
about:config
in the search type StartUp
you will see settings with the words Welcome and First Run
and some stuff about Override URL. Double click them.
A dialog pops up. Substitute either about:blank or your home page URL for what is in the dialog. Close Firefox.
==================================================
Note that I use settings "start with home page" and I use about:blank for my home page. If you put in the actual url for your home page and change the setting then you'd have to change it each time to match it up. It's probably better just to have it at about:blank as a blank page is less annoying IMHO than that thank you page.
Right now I'm using FF 3.6 RC2 and I got rid of 3.7Pre as the snappier page load is only a fraction of a second and what it lacks are features I use. But one good side-effect is if I do try another version or beta because I already have those settings in my profile I don't get the Thank You page or Welcome on first run(doesn't change the size of my browser window for one thing.)
