Multiple instances of Firefox

Hello! On the last conference call I mentioned that one can 
simultaneously run multiple instances of Mozilla Firefox with different 
configurations. This lets you test the browser's behaviors in its 
default state without interfering with the configuration you use for 
everyday work, and also lets you test different versions at the same time.

I used the instructions at 
http://www.mouserunner.com/FF_Tips_Multiple_Fx.html. The key steps are 
creating a batch file that starts an independent instance of Firefox and 
creating one or more profiles for configurations you want to test.

That site's author, Ken Saunders, is legally blind and also manages a 
prominent site devoted to Firefox accessibility 
(http://www.accessfirefox.org/).
