Cannot setup passbolt 2.11 in Firefox 100

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 should consider to upgrade your passbolt server to a more recent and secure version.

Best,
