Hi, for a long time Firefox was seen as slow by windows users when it was in fact Windows Defender slowing it down artificially to "check its activity" - while at the same time on other OSes it was actually faster and more lightweight than Chrome. I think that’s also the reason people downvote you - Firefox isn’t perceived as slow by the wider privacy focused user base (or they don’t care) - even though at some point it might have been on Windows or webpages are still better optimized for Chrome.
