So sorry to hear about your experience! Would you mind submitting a bug report on GitHub? I take feedback seriously and am working on a number of improvements right now that might help -- unfortunately I work multiple jobs and my capacity for this project tends to fluctuate. ~ Ari

Hey there, so sorry to hear about the issue! Can you try uninstalling and reinstalling the extension? There's some additional validation on the settings I had to add to resolve some bugs, which is causing this issue. Feel free to file an issue on GitHub (https://github.com/arimgibson/deadname-remover) or shoot me an email at hi@arimgibson.com to get some more troubleshooting help! ~ Ari
