What configuration files are uploaded to Firefox Sync ?

Every time you sync, what files inside your Firefox profile folder get synced with those stored on the Mozilla's servers? What information does each of them carry and to what sync category do they correspond (i.e I suggest that places.sqlite correspond to bookmarks and history).

Hi pgmank, I actually do not know the specific files, however I would imagine they would correspond to the feature that is turned on. Place.sqlite for history, bookmarks, then tabs would be active session files in the session-restore folder. passwords are signons.sqlite and logins.json.

However I do not know if they are stored in the same format. The sync uses an open source weave to sync between the sever and the client. All of it is really json stored formats

More of the storage format of old:

New format is somewhat documented in the build your own server for verison 1.5 that came out in version 29 of Firefox -> https://docs.services.mozilla.com/sto.../apis-1.5.html

Please feel free to ask more about it, finding help for this can also be asked in the #sync irc channel.
