I'm a Firefox guy. With an unusually slow dialup connection as my only link to the interwebs, the difference in speed between Firefox ans IE is noticeable and remarkable.I haven't tried the other newer browsers. Our friend and colleague Stereoman once said:
Friends don't let friends use Internet Explorer
and yes
So when friends ask me what browser to use, I say anything but IE. And as I do have control over what people in my department use, I smack their hands if I catch them using the hated browser for anything but system updates.
My son in law (who writes computer programs) said IE is evil.
My kids finally removed it from my computer and said "Mommy. No more!"
Talk about viruses not to mention slow.
