[citation][nom]ekubaskie[/nom]Best thing I've noticed about FF4 is that it gets the heck out of the way. Best browser, IMO, is the one that uses the least display space per feature, leaving more room for content.[/citation]
That's funny, because IE9 takes up less space by default than FF4, even when you put the tabs on their own row.
I'm looking at a side by side comparsion of the two browsers right now with FF4 set directly over IE9 and Chrome set over FF4. Chrome, without the bookmark bar, takes up marginally more space than IE.
Of the three browsers, IE takes the less space. When you add the bookmarks bar, Chrome takes the lead by a fraction of a milimeter and IE still leads FF by about a milimeter.
Are these sizable differences? No, but I have all three browsers pinned to my taskbar. FF is superior for useful addons, chrome is useful for certain websites like MasteringChemistry.com (which doesn't function properly on IE), and IE is the fastest on my computer due to the hardware acceleration.
I use IE for most websites, like Toms, Cnet, IGN, and a few others, I use Chrome on websites that don't work properly on IE, and I use FF to download youtube videos or other things and not much else. It's slower than both IE and Chrome and it takes up the most space.
I say, screw browser wars; have them all installed so you can take advantage of one's strengths and have options to avoid its weaknesses.
As an aside, I love how in Windows 7 Safari's close, minimize, and maximize buttons, the ones that usually sit on the left side, get reset to be on the right side. Originality fail.
