I use (actually use) about 35 plug-ins, around 50 user styles, and a few Greasemonkey scripts. Until Chrome gets all those, no way I can use Chrome. I've customized my Firefox experience so much, most people can't even recognize it. No way I can do that on Chrome. And in Linux, I run Firefox totally in a ramdisk, so it's ridiculously fast: http://ubuntuforums.org/showthread.php?t=1120475
Your need for plugins, styles, and scripts are the exact reason why the author claims Firefox has jumped the shark. It definitely can't feel 'right' if you need to customize it so much.
Everyone has different needs. Mine are not the same as yours. I used Chrome for several weeks, and it didn't meet my needs at all. With no extensions, I was unable to do 1/10th the things I do in Firefox.
It's not a bad browser, but it's extremely limited. I hope this will change, as I'd like more competition, but Chrome simply doesn't do the things that my extensions in Firefox enable it to do.
Also, some reading up on why FF has the extension model, and that not everyone uses a browser the same way, might be instructive here.
