I previously shared a simple disposable email tool focused on privacy (no tracking, no signup).
https://nullmail.cc
Now I've released extensions for Chrome and Firefox to make it easier to use:
- Generate a new address in one click from the toolbar
- Manage temp mailboxes from the extension (until they expire)
- No need to open the site each time (although the extension does open it)
- Same approach: minimal, privacy-first, open-source backend
