Anyone else see the heat map of the Back button being one of the most-used elements, and far more used than the Forward-button, and flash back to much, much earlier FF designs where the back button was, in fact, larger than the forward button and more prominent than most other UI elements? Just Googled, actually, and it looks like 3.0 did that. 2008. Sigh. Also, as a dedicated UI-depth proponent, I find myself in the awkward position of being the "no, not like that" guy re: the new tabs. They're jarring and don't seem like a coherent part of the design. More depth, yes, please yes, but with more purpose & thought behind it.
