I've never had any problems with firefox.
1) FireFox's speed alone is much nicer then IE.
2) FireFox is my default broswer, and i've never had any problems with opening the browser off my desktop and into the homepage (google) Opens in a blink of an eye for me.
3) Any heavly graphic site, like zelaron loads 10x faster then IE does.
4) I can adjust my toolbar with my favs ect... Not understandiing why you can't i'm using FF 1.0 PR.
5) Firefox has never crashed on me once, never. I've been using it for quite some time now
6) No spyware, no popups. I never get as many pop ups as IE gives me. Though a few do sneak in, but i can't blame FF for that, as its not easy keeping up with all the methods of popups. As with IE. If i open about
:blank i get a fucking popup. When i vist some unnames FXP sites in IE, i go threw hell. In FF never...
7) Opera Sux, (advertisments WFT??? i will not pay for a broswer as you do with opera to get rid of the banners)
8) FF's searcg funtion is much nicer, and the ability to Highlight words is a nice feature i use often when coding.
9) Tab browsing is just great, i'm always tab browsing, and you can use CRTL+TAB to go between sites and have 50 of them open in just ONE window.
10) The ablily to change the font size of websites is nice also. Some sites use 8px in there CSS and in IE you will see it as 8px. As in FF you can change that for people with poor vision.
11) Its not owned by Microshaft
You say your a perfectionist and everything has to be perfect. Well if coders code in true XHTML Transional then they shouldn't expericance any problems with tables or cells going out of align. Just use
http://validator.w3.org/ They found 135 errors alone just for zelarons front page. Not trying to flame your coding skills or anything, as you have always helped me when i was in need of help. And are a great experiance coder, sometimes wonder why you don't write your own software and sell it.

Anyways, just wanted to add my $0.02 in as im a FF user.
