I've hesitated for a long time to go from IE6 to IE8 because I couldn't confirm that the "accessibility options" would be as good, in other words that I could blow up print as well, and keep the color arrangement with white-on-black letters. I won't just assume IE8 is better in every way, including this one, because "upgraded" sites seem to make things harder on people with eye problems, and I'm suspicious of "upgrades".
The "different browser" thing's always confused me. I have interference with my concentration. I'd have the same concern about how print and the page would look I guess. I think I tried dowloading this massive amount of "stuff" for some other browser years ago, then couldn't find things to click on to use it successfully. All that is still taking up space on my computer.
