Mozilla, I don't know if you can do this — and it may require a major upgrade to a future Firefox release — but here it goes anyway . . . What I'd like to have is User control over my entire Firefox viewport (window): I'd like to flip the layout, or if that's too ambitious, at a minimum have the option to move the URL bar (or "Address Bar" or "Navigation Bar") to the BOTTOM of my viewport. To be perfectly frank, I'd like to have exactly one row at the top — my main FF menu — and the ability to move everything else to the BOTTOM of the screen where it is less of a distraction to my reading: bookmarks, icons, custom toolbars, customized search toolbars, etc.). Thank you for the opportunity to request this feature. Love FF.
