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 pr…
umm... I don't know if this works on mac too, but at least in the windows Firefox, you actually CAN use the address bar as a search bar. So why two bars? well the search bar also lets you CHOOSE your search engine, unlike Chrome which hardwires you to google. Yes yes, you might say but why would i want to search anywhere else? Well just like you hate having to actually GO to google to search on google, people hate going to wikipedia or wolfram alpha or ask.com etc etc before searching there. So it lets them query their engine of choice right from the bar. Oh and depending on your version, the address bar automatically searches on the engine selected in the search bar.
Now since you are a fairly old user of FF, i don't really understand the need to tell you all this, ut i just felt your nitpick about the searchbar saw this "feature" as a "design flaw"
