Thanks for confirming! Good timing — I just shipped exactly that: the button dims by default now, and hovering it shows a small × that turns it off on that site in one click, no settings menu needed. It's live now on GitHub and Firefox (AMO), and submitted to the Chrome Web Store — that review usually takes a few days. Will ping you when Chrome catches up, if you want.

You were right about the button, and it took you leaving to make me see it. Version 23.10.0 has a quiet mode: hover over the button and click the small "−", and from then on it only shows on pages that already have comments, or where somebody replied to you. No pressure to reinstall, but thanks for saying why you removed it. That's the most useful feedback there is.
