Firefox for life!
OT:
Don't really care about darkmode to be frank, would not care if I had the choice either.
Likes? Maybe. There's some irritating behaviours that "likes" promotes such as fishing for them and the weight a well "liked" post recives. Other than that I agree with the "don't feel like commenting" part, though since it's a thread I'd assume a comment with a quote would promote the post more than a mare like.
