- Address you enter disappears when you hit enter, doesn't reappear until the page loads. This is a problem if the page spins for a long time; it can be indistinguishable from a total failure.
- Type-ahead will occasionally find matches like "ha" -> "Hacker News" despite the address being "news.ycombinator.com" which is good, but... When you type the "c", that result will disappear! It's really unpredictable and that makes it hard to use.
- The status bar's "..." replacement can be good, but it occasionally elides the important part of an address, like "...blogspot.com/..." Not useful.
That said, Chrome is vastly more usable (on OS X) than FF just because of its speed and stability. I only use FF for Firebug now.
