789913 - Bookmarks of Firefox Sync lost

Status: UNCONFIRMED

(Firefox :: Sync, defect)

Description

[ffkevin3]

User Agent: Mozilla/5.0 (Windows NT 5.1; rv:8.0.1) Gecko/20100101 Firefox/8.0.1
Build ID: 20111120135848

Steps to reproduce:

I've tried the following methods, but it still doesn't see "Mobile device" folder:
* sync bookmark with the server (I'm afraid that the blank already replaced the data on the sync server)
* restore the autosaved bookmarks file *.json
* move places.sqlite to another computer



Actual results:

I'm using Firefox Sync to sync the bookmarks between a desktop and a tablet. In the desktop, the bookmarks include 2 parts: all bookmarks by Firefox Sync is updated in "Mobile device" folder; another part is bookmarks that add/change by desktop and is unchanged by Firefox Sync.

Last night, "Mobile device" folder in desktop is lost suddenly without any update or error, but other bookmarks didn't lose.



Expected results:

Does Firefox backup their Firefox Sync server everyday? Would I request Firefox Support to restore my Firefox Sync data on the server back to 3 days ago? Thanks!
