Ask HN: Which browser add-on for Hacker News do you use?

The first thing I need is a user-block feature. (HN has done an impressive job at nurturing civility, but it's time.)

I saw a promising-looking add-on for Firefox, but it had only a few users so far, and there was a blob of Wasm in the `.xpi` that was a barrier to a very quick skim of the code.
