iCloud for Windows erkennt die Installation des addon nicht. Daher keine Lesezeichen Synchonisation möglich.

does not work

No hay manera de que se sincroniza con iCloud, no admite "aplicar" en "ajustes de iCloud" (Windows 10) después de descargar la extensión.

Thank you

Sincroniza perfectamente con iCloud

Used to work, now it will not work at all. When you select in iCloud settings to sync with Firefox, the ICloud app tells you that you must install the iCloud extension in Firefox, which I already have from before, and then it never accepts or keeps the box checked in the iCloud app. Have tried removing the Firefox extension and re-adding to no avail.
