This addon has always worked wonderfully, however, since a week or so it has issues with it intermittently not working. It also stops working after ten seconds or so, meaning I have to refresh the page before I can activate/deactivate the addon. I believe this is due to a conflict with the latest Firefox update and I hope it gets fixed soon. It's a fantastic addon when it works!

EDIT: It seems to be working now, thanks for the update! Though still, there's also the problem of the addon not working with Alternate Player for Twitch.tv (chat is hidden and Shut Up can't be turned off), but if you don't use that addon, it works well.

Previous review: I can't recommend this as for now. I loved this addon and used it for years until it stopped working reliably anymore after the recent update. Something I noticed is that it would stop working after a few mins viewing a youtube video. I haven't tested if this only happens with videos or viewing a page in general, however. I only had ublock active at the time.

I've been using Comment Blocker for awhile on Chrome and just installed it on Firefox. Works like a dream on both browsers. There are several sites I love to visit, but the comments section are so vile that it ruins the experience and makes me tired of people. This add-on is a game changer and I can't recommend it enough. I was surprised to see how different the experience is and how much better I feel without suffering through everyone's opinion on whatever today's outrage is.

Not working atm? Otherwise the one Firefox plugin (and iOS app!) I couldn't do without.

Excellent. Thanks Ricky !

Peace and quiet. Thank you! Just wish the extension would have the obvious name: "No Comment".

This plus Ublock Origin plus NoScript equals Usable Internet.

I can't toggle the comments in Twitch. If the extension is enabled, the chat is gone, and toggling the icon changes nothing.

I am no longer depressed, thanks to this.

I love the concept and it does exactly what it says on the tin: block the comments. Except that the 'click to show comments' doesn't work and the only way I had to do that was to uninstall the extension so unfortunately I can't give it more than 2 stars

One of most useful extensions nowadays (for misanthropes like me)

Does not hide anything.

Click install button, comments gone, mood better. What more can I say? Really simple and you can reenable comments with a click of a button too.

Doesn't seem to work with Quora, LessWrong, or Tokyo Otaku Mode, but otherwise seems to work very well.

You don't necessarily need this extension if you have Ublock Origin installed (which features an element picker that can do away with virtually any comment section you come across) but if all you really care about is blocking the comment section universally then this is all you need.

So far, so great! Thank you, I can finally scroll through my recommended sidebar without being subjected to idiotic comments on YouTube. When I bother wasting time to respond, YT deletes my posts while leaving the troll garbage up. It's so much better now.

Simply Love it. Works as advertized.

Farewell, vitriolic, idiotic wasteland. Such a distraction, such a depressing thing to contemplate. I can't believe I didn't install such an add-on YEARS ago.
Finally...

Has its quirks but it might be the best add-on since sliced bread!

This app saves you from imposing of meaningless comments. I think, when I follow journalists or another creators I do not follow random people who write comments which I can't hide. Thanks you, Ricky Romero, for this app.
