I'm using Cryptonite by Metacert to be protected on steemit.com and busy.org. This extension for chrome and firefox works great. As the original site is verified and checked, all new phishing sites are recognized automatically.
Steemconnect.com is not verified until now, but hopefully soon (has to be done by the owner of the project).
I think there's another extension out as well for Chrome. The more the better (as long as they're not phishing themselves). We've got a full out infestation here.
