I made a userstyle that works way better, with more or less than 3 columns, and also fixes the issue with overly aggressive ellipsis in bio fields: https://userstyles.world/style/4743/spacious-mastodon - it works with firefox no problem, but maybe older browsers won't like it idk. If you're on sites other than mas.to or mastodon.social, you have to add that to the domain list first (and tell me on github if possible)

but yeah, this works as advertised.
