The content of the URL field is dependent on the tab. It arguably makes far more sense to have this strong relationship represented by containing the URL field in the tab itself rather than having a global URL field in one part of the window with content that changes as different tabs are selected in another part of the window.

That makes sense, however, I don't spend time looking at the URL. I look at the tab titles much more than I ever look at URL's. Additionally, to the common user the URL is a mysterious, meaningless thing anyway. They are more concerned with what the title of the page is.

Having to look over and past the URL bar to see what the title is, or having to look over the URL bar to select a tab, then back down past the URL bar to the page is less efficient visually.

I'm sure there are pros to the tab placement in Chrome, just as there are cons. Personally, it just isn't for me.

Tabs are on top in FF4 per default: http://blog.mozilla.com/faaborg/2010/06/24/why-tabs-are-on-t...

With at least three ways to change it to tabs on bottom.
