For those who don't know, it's a browser extension that marks a link to a group or person determined by how they act towards trans people.

I personally like this concept, but after reading the reviews on its Firefox add-ons page, it let me a bit worried. I found a Reddit post with one person commenting that someone marked their friends' blog as unwelcoming due to personal beef. On that same post, people were writing about how they used it just as a "suggestion".

So, returning to the question in the title, do you personally find this extension reliable/usable? Does it could have anything that should be worked better?
