I cannot recommend this add-on anymore and i suggest anyone who has it to uninstall it.
Recently the creators and moderators have started marking anyone who makes Trans Man, Intersex or Trans POC positive posts as TERFs, despite the fact that the people should be marked as trans-friendly. With the clear change in views making the creators themselves TERFs, this add-on is not a reliable source of distinguishing TERFs from everyone else.
If you are planning to add this add-on to your browser, you're better off making your own, as the creators cannot be trusted anymore.
