Both Firefox and Chrome has sync features, but they dont seem to work the way I want. Both Firefox and Chrome is having a top level grouping of the bookmarks, "bookmarks on PC" and "bookmarks on Android". And from Android the PC bookmarks are read-only. I can see them and visit them but not edit them or extend the collection with more bookmarks.
How do I add a bookmark from my Android device (in Firefox or Chrome) to my PC (Firefox or Chrome)?
