I'm a trans woman, this add-on has been excellent at letting me know who's safe and who isn't. All the complaints about "false" markings, and yet I've never come across a false marking yet. This tool is primary a way of marking transmisogynists, and if you're marked red and/or mad about this extension... you need to take a deep reflection of yourself rather than continuing to show your hatred of women sharing their experiences and trying to stay safe. Thank you to the developers and to all my sisters!
