Used to be phenomenal, then slowly over time became utterly useless. People whom I followed on social media became marked as red for speaking out against transphobia, whilst people marked green spouted hate. Unbelievably un-moderated and a useless extension in 2025.

best addon ever, has saved so much of my time and sanity. generally very accurate, despite what transmisogynists may say!

As it is now, it's very flawed. Many people are falsely marked as transphobic constantly.

despite what the devs may say, the extension is pro-radfem and anti-trans; trans men, transmascs, and nonbinary people are marked as transphobic for existing and fighting against bigotry. not even the transfems and trans women it seems to be oriented to are safe; if they don't follow the radfem thinking line, even they will get marked red.

I've seen numerous false positives reported here, many on radfems who are openly and repeatedly transphobic towards NonBinary people. I've also seen many NonBinary and intersex people marked red for seemingly no reason.

On top of that this extension doesn't seem to be updated anymore and is causing issues in the UI of certain sites. Noticed graphical glitches in YouTube already. This is definitely an addon to avoid.

this addon is outright unreliable - trans-friendly sites are marked red (transphobic) while individuals who express hostility towards transmascs and nonbinary people are marked green (trans-friendly.) this addon is completely unreliable, and the bizarre marking of people as red despite not them being transphobic, or even despite them being trans-friendly, makes this extension effectively useless

i have used this extension since 2019 i think and for many many years i was grateful for it. it helped me identify terfs especially on innocuous posts where they said feminist things i would theoretically agree with (e.g."men have historically been favored by patriarchal society and that's why we need affirmative action"). but i now see this extension being used vindictively against other trans people who just have different opinions, being used to hurt and isolate trans women, men and nb ppl who don't say exactly the right words in the right order. in the shinigami guidelines, even your out of touch granny who is saying accidentally transphobic stuff but still has the spirit is considered "not enough to mark as anti-trans", but people are being marked in red for saying they support both trans women's fight against transmisogyny and other trans ppl's fight against transphobia, if they are seen to be not explicitly saying the transmisogyny is worse. even if that is slightly transmisogynistic, how is that worse than out-of-touch granny? why does the extension mark as green even people who are being actively transphobic about trans men and nb people?
"all trans men deserve to die" is 1. not the same vent as "all men deserve to die" and 2. a transphobic thing to say! and there are people marked as trans friendly who say these things!

i wish the devs would make it consistent-- either no hate speech about any trans groups, and/or a little misguided venting/uniformed statements are okay.

i'm just tired of watching my favorite trans women creators get marked red for no reason

this addon may have once been useful, but i can't recommend it at this point. there's far too many transmasc and intersex people who are marked as red for no reason and far too many transandrophobic and intersexist trans people marked as green who should be marked red for this to be worth using.

Downloaded this to see if the discrimination that's been brought to my attention was as bad as it was described to me. I have a tumblr blog where I post about clouds shaped like animals and lo and behold I'm marked red, I don't know how to be more clear when I say I don't post or talk about anything besides clouds shaped like animals. The only thing related to the queer community on my blog is my bio where I have "transmasc it/they" writen so people know what to refer to me as... so yeah... it does more harm than good and it looks like I need to make a new pin post so I'm not auto blocked for, let me remind you, posting pictures of clouds shaped like animals and I guess being a trans man

There was a time when this extension was helpful but it has long since past. Too many trans and intersex folks are flagged red and too many terfs are flagged green or completely ignored. It does more harm than good and spreads more hate than protection. Another review lever was right, you can't trust a colour coded hyperlink. You need to make decisions for yourself and this extension is not a tool to aid you with that

Contrary to what people claim, I have never once seen a false red flag. You can easily investigate the account, and find something horribly transphobic, a lot of the accounts claiming to be false flags straight up believe that biological sex is an immutable reality. (Which is... bad. Regardless of if you're trans yourself.)

Used to be great, but I've noticed way way too many trans people flagged red and I have to uninstall it because it's just misleading now.

SE works excellently. There is significant negativity surrounding it, primarily from transmisogynists uncomfortable with their bigotry being publicly declared. They consider hatred and discrimination acceptable as long as you couch it in progressive language, but that doesn't make it less disgusting.

If you're a transfeminine person, this extension will work excellently at pointing out anyone who would be weird about your existence.

Used to be good, with showing off Anti LGBTQ/ Queer phobic pages. Now the main page of Wikipedia is seen as "Red" (anti-LTGBTQI)

I suggest the maker of this app fixes this issue or perhaps finds a hobby. Perhaps Stamp Collecting or Meditation or UXO Collecting

I have been using this extension for a couple years now as an easy way to detect transphobes (which is important for me to do since I am transmasculine and do not want to interact with these people at all) but lately I have been highly dissatisfied with how many transgender people are being flagged as transphobic for no reason. It is especially horrible towards trans men, intersex people, and those who do not fit into the gender binary, going against the whole point of this extension (detecting ALL transphobia, not just transmisogyny like the five star reviews for this extension claim this extension is only for). Please do better.
