I'm always afraid when such UI changes are announced for Firefox. Thing is, I love how I currently configure Firefox and I don't want to loose the ability to do it. So wathever new defaults you choose for Firefox, please always provide a way to revert to what we prefere (even if that requires to use about:config). Here's my current Firefox setup : http://i.imgur.com/PwiPeDM.png http://i.imgur.com/PwiPeDM.png . I'd like to be able to keep it that way. I seriously don't care about round corners and stuff like that if that means I loose some control over how I can configure Firefox the way I like.
