As a qualifier, know that I am a pretty ignorant computer user.  I’ve used Firefox as my browser of choice now for probably three years or so.  The only problem I’ve been able to find with it is that it seems to eat a ton of memory, which locks me down at times when I have a zillion applications running.

Lifehacker pointed me to the opportunity to download Firefox 3 and provide feedback during the Beta testing that Mozilla is driving.  Since I have no idea what I’m doing nor if I should be downloading it, I proceeded (Lifehacker says that it is stable enough to use, so I’ve jumped in).  You expert users might want to do the same.
