I've tried many Opera alternatives since it started getting SSL errors on many websites (Linux version so I never got the SSL update), Otter turned out to be one of the best. I literally have only a single complaint about a very insignificant issue, when my "start up" is set to "show start page" Otter forgets that I had unchecked "show menu bar" after I close and open it again. It seems to remember this per session instead of as a global configuration and I always start with a clean session.
