I just updated to firefox 14 and it’s working very well.  It has SSL connections when you do a search which is a very good feature.  It has cross platform plugins disabled so you don’t get browser plugin malware.  I was using chrome for a while but have gone back to my roots.  I really like the firefox sync so all my bookmarks on the browsers on multiple computers are all auto synced.  And firefox does not consume a ton of memory to run.  It also fills out my forms better than the other browsers.
