SUMMARY A sync service is very handy in case one owns multiple devices. Instead of developing a completely new service, it is possible to use existing solutions, such as firefox sync. If it is also capable of syncing between falkon, firefox desktop and firefox android (especially firefox android), it will be much more useful. ADDITIONAL INFORMATION Eolie browser <https://wiki.gnome.org/Apps/Eolie> has a working implementation of firefox sync. It is available via additional optional packages, so anyone not willing to to have it should have no problem. Also hopefully, optional packages will also not cause any licence issues
