Let me start by saying that this add-on does do the job. No comments! That said, it does the job somewhat clumsily. I imagine that it's quite difficult sometimes to determine which content is comments and which is not, but I encountered a fairly high percentage of sites in which basic functionality, like displaying an article or searching, just would not work unless I allowed "comments". In addition it was a pain to tweak settings in any way other than turning it on/off temporarily, on the fly. I had to go into add-ons and then preferences to whitelist/blacklist. The preferences have shortcut settings for right click/middle click that would have alleviated this problem a great deal, but the right click always just brought up a context menu and I don't even have a scroll click on my laptop or mac. It would also benefit from the ability to control things more granularly, which would allow users to work around inevitable targeting mistakes. So I'm trying out other add-ons for now.
