Well, the comment is about Firefox not improving their browser and instead doing other things; I imagine the comments will continue until Firefox commits to improving their browser instead of doing other things.
Like, what do these commenters think they're doing? Just venting that their pet issues of FOSS isn't being worked on? What's that supposed to accomplish? What normal human being reads such a comment and goes like 'oh yeah thanks rude asshole commenters, I get right on fixing that!'??
I don't want HN threads to be just endlessly and breathlessly complaining about people not doing shit they want. Pay up or do it yourself.
