This app is decent but sometimes is used as a bludgeon by terfs marking the average trans/enby poc red. I won't say to uninstall it but do not implicitly believe that every marking it's ever made is true and unbiased. Sorry, but you're still going to have to do your homework if you want to know if someone is transphobic or not.

Does not work as it claims to. I've seen multiple radfem and well known terf accounts marked green, and vocally pro queer and trans friendly accounts marked red.

Incorrectly marks trans men, nonbinary people and intersex people as anti-trans in a way that can only be malicious

White transfems can say the most vile transphobic stuff ever and still be marked green, but any poc that's enby/transmasc/2spirit/intersex and calls them out for it gets marked red. Mhm. Uninstalled.

This extension used to be really useful but I've seen multiple trans people who are outspoken advocates for equality get marked red. I think this is becoming more and more easy to abuse. It also seems like specific to Tumblr there is this thing where trans men and nonbinary people specifically are getting marked red which makes me feel really confused and a bit unsafe??? I'll be uninstalling. This is why we can't have nice things...

edit: It also seems like POC are being targeted. Triple, quadruple yikes.

keep seeing intersex people and people who say that trans men face oppression marked red and people who are honest to god using 'theyfab' marked green. useless at this point

im far more likely to run into someone marked red who just happens to be not white, a trans man, intersex, or a combination of the 3 than an actual transphobe

It's been showing more and more bias against trans people who talk about trans masc, nb, and intersex issues (probably more tbh) for years now, but it's getting so bad that I assume a Tumblr blog marked red speaks up for those groups rather than assuming they're a transphobe. I've been keeping it anyway to help me remember which news sites suck, but it's become a detriment. This could have been a good tool, but I guess the mods, or the creator, or both have decided to use it in bad faith against their own community.

The users have bias against trans men, intersex people, and people of color. You have to experience your gender in a way that is "correct" to white transfemmes or else you get marked red.

what even happened here????

"If it sounds too good to be true.": The description claims to target "transphobic/anti-LGBT" content, but it doesn't. Nonbinary, intersex, trans masc, and POC are consistently flagged red. It flags binary white trans women as green, even as they call for the deaths of the aforementioned groups. This is a racist, intersexist, enbyphobic addon. If you identify with any of these groups move on.

yeah this has gone to shit.

I really loved this extension, especially when it came to people who might dog whistle their transphobia. But I've increasingly seen friends/people I follow who are either trans themselves (which, of coure, transphobic trans people exist, but this isn't the case here) or are ally's who get marked as red. This is genuinely heartbreaking, as this extension is something I've been using for years, and it was one of the extension I kept when I moved from Chrome to Firefox. But the lack of updates, and the fact that transphobes can use it against its purposes really sucks. I hope that the devs or someone else can pick up the pieces, but I think I'll uninstall this now.

It's gotten worse over the years. With the amount of false flags it has now it's worse than useless, it's actively harmful to trans people.

The 5-star reviewers are primarily TERFs, just an FYI.

Anyways, yes, this extention USED to be a valuable tool for rooting out harmful people, but nowadays it has become weaponized by TERFs to belittle, ostracize, and invalidate large portions of the queer community.
False flags are pinned against trans men, transmasculine, intersex, nonbinary, and queer people, as well as people of color. They are marked red simply for speaking about the oppression they face and their own experiences, meanwhile TERFs who openly call for the deaths, detransitioning, and rape of transmasculine people remain green, "safe." Tell me- how that is fair? How can someone like that be a safe and trustworthy person in the queer community?

This is not, and never has been, a tool to "call out misogyny." It is an outdated, jumbled mess of code that TERFs are using to make lists of people that don't agree with them. Don't use this addon.

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.

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.
