I have iceweasel too (no firefox), its called on my side a torbrowser and i see this:
from my /home directory
Code:
ls ~/.mozilla/firefox/default/bookmarkbackups$
bookmarks-2014-02-09.json bookmarks-2014-02-10.json
Code:
ls ~/.mozilla/firefox/bookmarks$
places.sqlite
both files, json and sqlite contained my bookmarks, not sure which one is important for recovery..
