When Xmarks disappeared I was stuck for a while. But then I installed a NextCloudPi server at home which was pretty easy and has a load of benefits beside, and found floccus. It was was not working when I first tried it, but Marcel has been chipping away at it beautifully and as of version 3 it's well and truly slick and a satisfactory Xmarks replacement!

"Do one thing and do it well"
This add-on does what it's advertised to do, very easy to setup and uncomplicated.

Thanks for your great work so far.
Gave you some little support on liberapay - and this is what other people explaining here should do as well - this an open source application developed by one guy in his freetime. I value that.

Firefox Android Support
The main feature currently missing for me is the firefox android support. This hasn't been done yet because of missing support of the API in firefox android. If anyone like me wants to speed up this feature - he can donate here:

Nach anfänglichen Schwierigkeiten läuft die Erweiterung inzwischen Perfekt und ist unverzichbar für mich! Herzlichen Dank nochmal für den tollen Support und die unglaublich schnellen Versionsupdates :-)

Thanks for adding folder/tag support! Firefox Bookmark sync has been iffy and XMarks really spoiled me until it went down the tubes.

Great app, Would love to see some Tag to Folder translation That way it becomes a whole lot more manageable with 500+ bookmarks. Multiple tags is the same bookmark in multiple folders. Works perfect in combination with Passman :)

Thanks to you, this add on is really convenient

Works great. really missing tag sync, but we'll need to wait for that.

Funktioniert ganz gut . Wünschenswert wäre noch die Synchronisation der Tag´s und auch eine Version die mit Firefox für Android funktioniert. Aber mir ist klar das das eher ein Problem vom FF ist . Da diese Funktionalität in aktuellen Versionen nicht vorgesehen ist.
Darum auch 5 Sterne .

works very well. Just does what it's meant for! Good work.
