I have tried following the directions given here:-
However, I am not seeing a Mobile Bookmarks folder on my PC's bookmarks section within Firefox 16.0.1 so do nto know how to get this working in two-way sync between devices.
Here's what i did. Assuming you've set up the sync process:
Bookmarksin the top right corner
Unsorted Bookmarks. This opened a new window for me where i could see a section called
Mobile bookmarksthat i hadn't seen anywhere else.
Mobile Bookmarksfolder to either
Bookmarks Menu, whichever you want it to appear under (Note: the
Bookmarks Menuis what we clicked on to start this process, i advise you try both and see which you like best).
Hope this helps!
