after xmarks this is the choice. it works... most of the time. as the only solution I would not recommend. have the backup ready or/and use the backup feature of eversync.
things that can go wrong
- merge: creates duplicates
- takes as long as 40sek (usual) up to 15min (at the moment) up to never finishes (on occasion)
things that would help you as addition
- bookmark manager third party
- FFs import / export as a backup
- FF freeze
do not
- use it with FFs Sync
it will not
- currate duplicates
- sort or edit or manage
it is possible (with pro)
- to store you backups online
