Profile backup does not work for me.

Peter Chapin replied

I'm using Firefox 153.0 on a Windows 11 desktop. I'm trying to use the feature that backs up my profile (bookmarks, history, and other data). When I turn Backup on, I'm asked where to store the backup, and I accept the default of putting it on my OneDrive. When a backup begins, an empty folder named "Restore Firefox" appears in my OneDrive, as expected. Firefox shows a message like "backup in progress." After a minute or so, the "Restore Firefox" folder disappears. After another minute or so (not immediately), Firefox tells me the backup failed and that I should try again later.

I assume the backup failed because the folder it was trying to use isn't there, but why did it get deleted?

There is ample space on my OneDrive and on my local system (100s of GB). I am using the ESET security software package, but it did not raise any warnings or errors.

Hmmm, I've tried that once and it worked. Perhaps the Browser Console ( Ctrl+Shift+Alt+I ) could say more about this error. Try creating a backup locally on your Desktop.

Thanks for your note. I tried creating the backup on my local drive, and that seems to work. So either the problem was related to OneDrive, or whatever was causing the issue has fixed itself since yesterday.

I notice that it makes backups quite frequently. Whenever I start Firefox, it makes a fresh one, and then again after a few minutes if I'm using Firefox. If I just have Firefox open without touching it, no new backups are made. I assume it is snapshotting the profile as it changes. Is that normal? The documentation suggests it only creates a backup once per day (but the document here says every 60 minutes... my experience is that it seems to be tied to active use).

BTW, Ctrl+Shift+Alt+I didn't bring up anything for me. Is that only something in the development version of Firefox?

This is a follow-up on my own message.

I discovered the same problem again when I tried to put the backup on my D: drive (a secondary HDD). So the original problem wasn't due to the target being OneDrive; it was due to the target being something other than the local C: drive. Note that my OneDrive folder is mapped to my C: drive, but of course it is cloud-backed, which I'm sure makes it look different.

Since the behavior appears to be that Firefox creates a new backup every few minutes when I'm actively using it, I feel funny about frequently writing and rewriting a 100 MB file to my SSD. Perhaps it's not an issue, but my preference would be to use my HDD... only that doesn't work.
