My favourite content blocker

I've used almost all the popular content blockers and this is the one I liked best. It is very customisable, and recent updates added the ability to block custom elements based on CSS selectors. Now I can block whatever I want... Which is awesome.

I'd say this is the best choice for power users. It may be overkill and confusing for a completely non-technical user, but if you want the power of customisation, I recommend it.
