If we start considering even those as optional, where does the simplification end? Then why don't we take out the bookmark bar, navigation bar, menu bar, status bar etc and attain supreme simplification by displaying a single text field which should lead to search. Surely the user can search for add-ons from that field and get whatever they want. It'll have the side benefit of helping users attain UI nirvana as well.
Go for it, show bookmarks on the new tab page.
It could certainly stand to be shrunk at the very least.
Yes please, I have my browser configured to no menu bar, saves a nice bit of space.
There's a popup when I hover a URL and otherwise I get to save space.
More on point, the add-on bar was a dumb idea and behaved weirdly. Good riddance. While a built-in real status bar would be nice, an extension to provide one is pretty good too.
