Firefox 29
I love Firefox -- for what it's done, what it represents, and what it helps guard against. I have fond memories of those early versions of Firefox (nee Firebird) that busted open the IE monopoly, and where hands-down the best browser going at the time.But it's never felt very good on the Mac to me, and it still doesn't. Here's a few early thoughts on this release, from the perspective of a happy Safari user, w/ a pretty (nit-)picky eye.* Separate address and search bars is old-fashioned. As a user, I don't want to have to make this distinction, and it's hard to imagine most users-on-street wouldn't find this confusing* The address bar is square edged while the search bar is round edged, which is displeasingly visually. (I realize this is because there's a convention of "search bars are rounded," but the inconsistency remains.)* Tapping the hamburger menu on the far right, it appears with a combined drop-and-fade-in effect, and then disappears instantly.This is jarring on the Mac, because it is exactly the opposite of native menu behavior, which is to appear instantly, and disappear with a fade. (I also believe the native behavior makes more sense: when you're tapping a menu, you want to do something, so you don't want to be slowed down by an animation -- just show the menu.)(Addition of a hamburger bar on the far right at all is suspicious; often it's a UI "dumping ground")* The "what's new" slideshow that appears at the bottom of the screen has to be controlled by clicking small  arrows, instead of just scrolling, which feels very outmoded* The scroller applies a fade effect to incoming content, but only to the text, not the image, which is jarring.* Multi-touch swipe to go back/forward shows no feedback! (Safari does this best, where the whole page slides away, revealing what's underneath; Chrome does a half-assed thing with arrows fading in, which isn't nearly as nice, but at least better than no feedback.)Pretty nitpicky, I know, but I recently read an article trumpeting this release of Firefox's incredible attention to detail.On the Mac at least, I think it still falls short.
