Firefox 77.0.1 mainly, Windows 10-64 v1909.
I’d previously seen confirmations of my (manual) backup to Google Drive as being successful. Prompted to backup again, the app stalled.
Following the de-bug guidance, I found a message in the console that, somehow, I had an experimental database and should update the app.
On starting the re-installed app, I seem to have lost everything and checking my Google Drive I have no backups - none - despite getting success messages within the app over the preceding months.
Unless I can recover my history - and make a successful backup - I’m out of here and steaming angry. Please note I have not turned off my computer yet as I’m hoping there’s a way to recover my history.
Your urgent assistance will be appreciated
