I'm enjoying the Firefox 3 builds, but the Awesome bar generally sucks, all around.
Most hackers will expect when they type something like:
you will get back a list of urls beginning with gma in your location bar. This is similar to the way that completion works on the command line and in our text editors, and is how Firefox has always worked up until now.
Instead, FF3 searches page titles, bookmarks, tags, recently visited urls, most visited urls, and does a full text search on these string rather than starting at the beginning of them. Great for people who don't know what a URL is, fucking unbearably annoying to someone who just wants to type two or three characters and be done with it.
I think the awesome bar would be quite awesome for some people, so long as it could be disabled. However, from the rumor-mill, it sounds like the FF2 url bar has been scrapped to avoid code bloat.
To me, this is just a sign of how Firefox is increasingly becoming an end user commodity, which encourages ass-raping developers in the name of more downloads. Sad... really
