I've been using Google Hit Hider, a userscript, for this for years. I can import/export my list, sites can be both "banned" and "blocked", I can de-duplicate and de-www my lists if needed, etc. It's very flexible. (Despite the name, it's DDG compatible as well) It's also completely free. What advantages does this have over Google Hit Hider?
