It's not just the tab bar. I use Tree Style Tab and so have tabs down the left side of my window and the horizontal tab bar hidden. However, my bookmarks toolbar is right under the URL and search boxes, and that toolbar is probably my most frequently used interface to the browser, with the search bar not far off. The URL bar is a distant third, but now a slight misclick opens the ohmygoditshuge URL bar area and then the bookmark toolbar I was probably aiming for is mostly obscured. Not only that, but clicking in the area above the URL bar then has different results depending on exactly where you click, but they range from not closing anything to closing the drop-down but still leaving the oversize URL bar partially hiding the bookmarks. None of them just closes the whole thing again, the way you would expect an expandable control to do when you move the focus elsewhere. "Infuriating" is not an adequate description for this change in something I use hundreds if not thousands of times per day. It really is as annoying as when MS Office switched to the ribbon UI.
