  • (2017-12-16) Paul Stanley: Confusing ugly UI, but it does work. I needed a way to add an Authorization header for a specific URL. For that purpose, this works perfectly.
  • (2017-11-16) Michael Enke: Modify "Accept" header doesn't work. Settings: "*" "Accept" "application/json,text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8" It also doesn't print to console. Chrome 62.0
