Thanks for the details.
Your problem is not Firefox but your passbolt server API who is too old, as @cedric said on another topic:
If you are running an API v2.x with the latest browser extension, this is an expected regression. The home page of the application has evolved and the legacy API v2.x home page doesn’t display the link to recover your account anymore.
You have 2 options:
- You can go to https://your-passbolt-url/users/recover and request a recovery token. You will then receive an email with a link to follow to initiate your account recovery.
- You can update your API to the latest version, the online documentation is complete and will guide you step by step: Passbolt Help | Upgrade
You should consider to upgrade your passbolt server to a more recent and secure version.
Best,
