How to run Firefox 3 and 2 at the same time.

If you're like me, you love Firefox and you can't wait for the full release of ver. 3 Problem is, if you try to run 3beta most add-ins don't work yet, and you might just hose what's already working for you.

Well, here is a solution that will allow you to run both versions side by side until you're ready to fully commit.

Create a New Profile:
You can create a profile exclusively for Firefox 3 in your Firefox 2 Profile Manager.
From your command prompt run:
c:\Program Files\Mozilla Firefox\firefox.exe -ProfileManager
Name it something like BetaTest so you know you are just testing it.

Download Firefox 3:
Download the latest Firefox 3 nightly build and install to a specific directory. (like c:\FF3)

Start Firefox 3:
Start Firefox 3 with the new 'profile' you created. The key here is the ‘-no-remote’ parameter as it makes Firefox start a second Firefox.exe process with the new profile.
From your command prompt run:
(firefox3 install directory)\firefox.exe -P DeleteMe -no-remote

You could also create a Desktop Shortcut and change the property of the shortcut so you don’t have to type it all in every time.
