About

This extension helps overcome CORS policy limitations ONLY on SuperAnnotate’s and localhost domains by modifying the `Access-Control-Allow-*` response headers.

You can enable or disable the extension by clicking on its icon.

Additionally, you can toggle which types of headers it modifies:

Enable Access-Control-Allow-Origin:
  - Default: Enabled
  - Header: Access-Control-Allow-Origin
  - Value: *

Enable Access-Control-[Allow/Expose]-Headers:
  - Default: Disabled
  - Headers: Access-Control-Allow-Headers, Access-Control-Expose-Headers
  - Value: *

Drop [X-Frame-Options/Content-Security-Policy]:
  - Default: Disabled
  - Headers: X-Frame-Options, Content-Security-Policy,
  - Removes these headers from responses
