Hi HN,
I'm heavy user of Fastmail's masked email feature, but since I don't use 1Password or Bitwarden, I find it cumbersome
to create masked mails by going to the Fastmail settings page every time I need one.
To streamline this process, I developed a tiny Chrome extension that allows you to create a new masked email through the
context menu with just one click, and autofill the email form field.
