You know, although I have the browsers in question for testing purposes (and site compatibility issues, incidentally), I never noticed the combining of the stop/reload button with the go button. That's how it's meant to work! Quite a few times I was annoyed I couldn't hit "reload" if the loading of a tab had failed. In Opera, I had two choices: Use the keyboard to press enter, or copy the url and then select "paste and go". I think a "go" button unnecessarily clutters the UI, though, so this solution would be perfect (though not necessarily the placement of the button). I wonder if a customized opera button could do this..

Tabs at the top, well they're all seeing it now, aren't they? That it just plain makes sense. The address is an item within a 'tab'. It makes more visual sense, although under the hood it's probably the same old UI thing which is told to redraw with a new url each time one switches the tab.

What I find worrying, though, is the distinct lack of color. I know the newer Opera skins annoyed me because the icons were all black-n-white. Way to go to make me unable to distinguish buttons at a glance! On this screen, I can see it's less of an issue, because beasically each item has its predefined position, but I'd like to see the bookmarks menu/manager, or a customized setup with more of the buttons immediately available.

My personal preference is also against disproportionate arrows (i.e. back button bigger than forward button). Symmetry appeals to me. And I don't want my browser to second-guess whether I'd not rather go backwards than forwards. But that's been with Firefox for some time, so it's a moot point I guess.

If Firefox has tabs like Opera, I'd love Mozilla forever.

Turn Page and Tools into an icon-only tab like the Home tab. Save more space.
