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

Seeing a few 1 star reviews but I feel like people don't understand that this extension uses people marking accounts as anti-trans/trans friendly to show them as red/green. I can count on one hand the amount of times I've had false positives, all you need to do is check people's posts, not whether they're trans themselves.

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.

keep in mind all the 1 star reviews are transmisogynists lmao. good addon

what even happened here????

a good tool to find out who's a misogynistic (specifically transmisogynistic) weirdo.

im sorry trans women.

"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.

If anything this extension doesn't flag enough people. Transmisogynists are under reported. People giving 1 star and claiming its run by TERFs are just mad that they can't harass trans women with impunity and consider men more important than women.

The negative reviews are almost entirely review bombing. I use this all the time, and have never had a problem with false flags. If anything I find things that should be flagged one way or the other going without a flag at all. 9 times out of 10 if you look at the profile that got flagged, you'll find why within a minute of scrolling. The transphobes (usually transmisogynists specifically, but all kinds of transphobes) who get flagged red love to complain about how bigoted and inaccurate this extension is and how it can't be trusted, but then you look and see them spouting the most hateful rhetoric about trans people, plenty of them even trans themself. It's not a tool for exclusively marking transmisogyny, but transmisogyny is transphobia, and when fellow trans people are anti-transfeminist, they rightfully get flagged red. TL;DR it works great and has kept me safe from transphobes, remember to flag accurately and block liberally 👍

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.

So far it's been accurate to me... I'll keep reviewer's inputs in mind though and hope to contribute...

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.

good addon, NEVER had any issues with false flagging

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.
