I mean, anything related to aesthetics is going to have some difference of opinion. Mozilla appears to have concluded it's the people who dislike the address bar who are a verbal minority, or they wouldn't have gone with it.

You'd think .. but no: Google is the default homepage, so they type in to the search field. It's mad.
Some have Bing as their homepage, if you've ever done IT training you might know the next line. They do it differently, they type "Google", click a link to go to Google, then type "BBC" (say), and click on the link for "bbc.co.uk". It's insane.
