Hi

Firefox Notes has been unsupported for almost four years: https://support.mozilla.org/en-US/kb/notes-status

The data for both the desktop add-on and Android app is stored locally on the device. It would only be lost if the app or add-on had been uninstalled.

Thanks, Paul, for the 411 re: Firefox Notes being stored locally on my W10 HP Elitebook 8440p. I lost all my Notes when I upgraded Firefox from 131.# to 132.0.

Where should I begin looking?

Thanks in advance for your help!
