Yes, voting down a legitimate comment here so that it's greyed out, thus making it more difficult to read, is a form of censorship.
As for Firefox's reputation, I think it still has a reputation for poor performance because, contrary to what you and others may claim, a lot of people still find recent releases to be slower than Chrome and other browsers.
It will never be able to shed its reputation for poor performance as long as it still suffers from those problems. And these problems will persist as long as the Firefox community continues to deny that they exist, or go out of their way to suppress discussion of these very real performance problems.
