Quite a lot of transphobic places aren't marked as such, but I guess it's just a matter of time before they do.

Works as intended, and rarely any false markings

Good for double-checking sources and identifying transphobic jerks.

Great. Just as long as you don't treat it too seriously. It's good for perhaps second guessing a source or commenter you see. Just don't take it as fact.

edited: it used to be really helpful! now it's, like, 50-50 on whether someone marked red is actually a violent transphobe, or just a trans man talking about transphobia they face or an intersex person using a label the mods don't seem to like. having to manually check every single time whether someone's actually transphobic defeats the entire purpose of the extension and it's also exhausting

makes browsing social media less stressful for me as a trans person.
