I wrote a web extension (currently available for Chrome and Firefox) that allows Fastmail customers to easily manage their Masked Emails. As a heavy user of masked emails, I'm always creating new ones for online services, disabling emails that are receiving excessive marketing emails, etc.

Features include:

- Create new masked emails

- Enable, disable, and delete existing masked emails

- View details about all of your masked

- Favorite your frequently used existing masked

- Filter masked emails by state (enabled, disabled, deleted)

- Fuzzy search across masked email address, description, domain, or email

- Edit the description and domain of an existing masked email

- Quickly copy details about your email to your clipboard

Hope this is useful for other masked email users! Feedback appreciated and welcome.

PS: still adding to and cleaning up the repo/readme/wiki but the extension is fully functional and ready to use.
