Web developers have to make sure their code works for the Firefox browser. I must admit to being surprised, in the past week I've run into two sites which don't work on Firefox, and that's really not a good idea. After all...
Firefox reaches 18 percent of corporate desktops
and...
So, based on XiTi and IWS’s statistics, roughly 1 in 5 Internet users prefer Firefox, assuming Internet and web usage are correlated.



I love Firefox and never use IE if I have a say so in the matter.
Our home computers got hacked HARD a little over a year ago when they all ran IE. It took me over a week to resurrect them from the dead. One of them, may it rest in peace, never really came all the way back from the dead and eventually went to that big computer graveyard in the sky.
After the other two were fully resuscitated, I put Firefox on them and deleted all the IE icons thereby forcing the rest of the family to use Firefox. IE is still there, the family just doesn't know how to find it. Thank the gods.
Hey, this ain't a computing democracy here at home! I'm the IT person here at home so they only get to use the hardware and software I approve! :)
Since moving to Firefox we have not been invaded even once. My regular security scans of the computers always come back absolutely clean.
Long live Firefox!
