I use the built-in sync service in various Firefox forks to sync bookmarks/history/tabs, using the default Mozilla servers.

When I went to “Manage Account” to review and prune the devices (“services?”) linked with Mozilla Sync down to what I’m actively using currently, and noticed “Mozilla Monitor” in there.

I can’t find any info on why Mozilla Monitor required sync credentials, and I don’t remember Mozilla Monitor telling me it would be gaining access to my sync data, nor can I find any way to review what data “Mozilla Monitor” has access to.

Any ideas?

For now I’m signing out that entry, while I consider other sync options.

Edit: changed title from ‘Mozilla/Firefox sync - why is “Mozilla Monitor” a signed in device?’
