I like Chrome in theory, but I've just found it to be a bit buggy. Sometimes it won't fill in passwords, even though I've told it to remember the password, and the password shows in my list of saved passwords. The browsing speed is generally fast, but I've had Chrome randomly hang in the middle of loading pages until I manually refresh (and this has happened in Windows, Mac, and Linux in multiple locations). The extension that allows for opening new tabs on the right instead of next to the current tab doesn't function exactly like about:config modified Firefox.
Ultimately, the supposed speed gains of Chrome aren't worth it for me. Firefox is fast enough, and it behaves exactly the way I want it to. I like having the address bar be an I'm Feeling Lucky Google search and having separate search engines in the search field for Yelp, IMDB, Dictionary.com, etc. Firefox sync is great.
I won't recommend it to everybody, but Firefox is still the best browser for me.
