Was thinking of making the switch to FF yet again, and this seemed a handy way to sync notes, also installed XMarks because the dev insisted (be careful w XMarks - sync'd bms are public by default); did not sync at all in spite of forcing syncs; and lost many notes in the process. Back to a more reliable browser eco system - chrome with Text.
FF always had issues with sync, this time around with latest versions, nothing sync'd in 2 days, maybe bcoz they are migrating. Whatever, had it FF this time around.
