I use Firebug for all the front-end development and debugging. Unfortunately its not yet available for Firefox 3 beta. Its not just Firebug, there still are quite a few other useful extensions that have not been updated for Gran Paradiso(internal name for Firefox 3).
But at the same time, I have my own reasons to test/try out Firefox 3. So I found out a way to run FF2 and FF3 simultaneously. Following are the steps to do so:
(I assume that Firefox 2 is installed on your machine. If not, click here to install it.)

Step 1. Create a new profile for your Firefox 3 installation.
Go to the profile manager of firefox (type “/path/to/firefox.exe -profilemanager -no-remote” on the command prompt) and create a new profile called FF3.

Step 2. Download Firefox 3. And install it.

Step 3. Right click on the Firefox 2 icon and go to Properties. Add the following to the end of your target “-P default -no-remote”. This will make sure that whenever you run firefox 2, it opens in your default profile.

Step 4. Right click on the Firefox 3 icon and go to Properties. Add the
following to the end of your target “-P FF3 -no-remote”. This will
make sure that whenever you run firefox 3, it opens in your newly created, FF3
profile.

Thats it. You are done. Enjoy.
