[nsagent]

I was previously using Wipr 2, but got tired of the fact that it would block things I didn't want and there was no recourse except disabling it wholesale (for example, I noticed it blocks any element with an id of 'privacy_policy' or 'privacypolicy,' which I ran into when actually trying to read the privacy policy for a service I use).

wBlock fixes that by allowing you to have custom rules. It also includes the ability to run userscripts, so I no longer need a separate extension for that.
