Restored bookmarks because almost ALL were missing (Firefox).

Restored bookmarks because almost ALL were missing (Firefox). Installed EverSync Jan 1 in Firefox (Windows 7 64) and Android phone.  Did not make any mods to bookmarks imported into phone (and they still exist there).
Restore options show progressively smaller bookmark backup totals beginning yesterday at 10:25pm then bottom out at 7:17 this morning (1645--1282--223).
