Revert to old firefox look

Hi

You can choose you own theme from our add-ons site. If you are looking for something close to the default theme, you may want to try:

While themes address some of the issues, and I appreciate your response, they still didn't fix all of the quirks I didn't like about the new design. I just found out about `browser.nova.enabled` in `about:config` though, which actually just reverts to the old theme

That's better—we're saving space horizontally, but it's not enough. Tabs haven't been tabs anymore—they've been buttons—for quite a few versions now. A tab should be flush with the page, not above the address bar and without any space below it. But these buttons have completely lost their usability. Referring to “tabs” when what we see are buttons is a linguistic error that leads to confusion. A tab was once a feature whose logic has been sacrificed for aesthetics.
