FF fanatic here too. IE still craps out on me no matter how many times they 'update' or 'fix' it - just adds more bugs. FF has always been stable and updated for me. For web design and SEO FF is king.
Well, everybody have their favorite, mine is Opera. The fastest and coolest browser. FF is also good.
In my opinion, Internet Explorer is the most terrible browser ever invented, and Firefox is awesome. It has sooo many add-ons and plugins and all kinds of stuff for it. I am using chrome right now, because its sleeker and cooler IMO, but if I wanted to do the most functional things, I would use FireFox.
Firefox is the best for customizability. However If you do lots of tab surfing Chrome comes out a clear winner because its multithreaded. Firefox can hog all your system resources even after closing the tabs.
I would say Google Chrome is the best. it out perform CPU and RAM usage any other browser.. try having FF with 10+ tabs running for a few hours you'll see what I mean. Now try the same with Chrome and you'll see the huge difference
I think firefox is better than IE with addons but when it comes to speed IE is best. Opera is worst browser of all times.
I love Firefox, I think it's about one million and a half times better than IE7 and about one million times better than IE8. One great addons is AdBlock Plus. It's quite customisable aswell. I also use Thunderbird for email, fast and simple and it's also easy to manage multiple accounts.
Firefox does everything you need a browser to do + it saves your bookmarks and has great add-ons - awesome.
