I think it's time to switch back to Firefox, Chrome is freezing a lot for me lately (Aw, Snap!). The only thing I miss is the universal search/URL/autocomplete bar, is there an extension for this?
I can't speak to the quality of it, however. I use ctrl+l for URLs and ctrl+k for search, and am so used to it I don't even notice (especially since Firefox's AwesomeBar tends to have better results for me than Chrome's OmniBar).

Once you are used to it, in my opinion, it puts the other address bar goodies to a shame.
