Looks more "Windows 7"-like on here, in that there's more of that smudgy glass effect. Looks prettier when active I think, although when not the glass becomes more transparent and since there's so much of it, toolbars from applications underneath it seem to show through a lot, which creates a lot of visual noise. That's not entirely Firefox's fault, and it looks okay when it has focus, so it could be worse.

Seems faster to start, although it's disabled every addon I had before, so hardly a fair test.

In general it seems to be more like Chrome. Which I think is probably a good thing - if Chrome has demonstrated a better way to do things, I don't have a problem with Firefox following their lead.
