Firefox Sync works fine on my iMac and iPad2, but not in Ubuntu MATE 16.04 or 16.10 on a Raspberry Pi 3.
I can register it as a device but Sync only downloads some of my 800+ bookmarks and does not include the folders in which they were arranged.
This is very frustrating and precludes using Firefox as the primary Web browser in MATE. Anyway, FF is very slow compared to Chromium, but my bookmarks are important to my workflow.
Any ideas of a fix, or is this not yet possible?
