Firefox all the way!
I like Firefox because it's more user secure and user friendly than IE. I've never bought into the idea that it's faster or more resource friendly that Internet Explorer. Whenever I check, Firefox is always using a ****load of RAM, especially when I've got a half dozen websites open with Flash animations, video streaming, etc.
My main problem with Firefox used to be that it was ridiculuously slow to start up. I'd click the Firefox icon on the Quicklaunch taskbar and it would start 20 seconds later! That's no good!
But that's not a problem recently. Maybe recent Firefox releases have done away with ever caused it to start to slowly, I don't know. But it was only ever a minor annoyance.
I've currently got 2 PCs - Windows XP and Ubuntu 6.06 and I've got Firefox setup as the default browser on both of them. I like Firefox in Ubuntu simply because it was my browser of choice anyway and it's the default browser in Ubuntu.
Having used it for well over a year now, it's so obviously a superior browser to Internet Explorer. Not because it's faster. But because it's got tabbed browsing. And it's far more secure. And it's got so many cool extensions. And it kills so many popups automatically. And it's got the abilitiy to tweak the settings to kill even those stubborn popups that get by. It's superior to Internet Explorer in oh so many ways that it astounds me when people insist that IE is the overall better browser.
Te only advantage of Internet Explorer, at least from my point of view, is that it's got a near monopoly on the browser market and some websites only work with it. Which hasn't got anything to do with it being a good web browser. It just goes to show you how a market monopoly can lead to forcing people to conform to your non-standard "standards".
To hell with Microsoft Internet Explorer, that's what I say! The more quality web browsers on the market the better!
edit: My dad bought himself a dirt cheap Dell PC about six months ago. He bought it as an upgrade to an 8 year old P150/32Mb PC he used for MS Office stuff. I set it up for him in such a way that Firefox is the default browser and installed extensions like the TabBrowser one that launches all sites apart from popups in tabs. He loves it and is totally familiar with in such a way that he's not even aware of the existence of Internet Explorer. Which is how it should be. I'll only ever show him IE when he calls me when he comes across a website that's "broken" in Firefox and needs IE for the "broken" website to work, which hasn't happened yet.
