Hello. I am using Firefox on two desktops and one Android phone. The two desktops are synchronized well, but on the phone, when I open the "Desktop's bookmarks" folder, I can see just a several recently added bookmarks there. Tens of the old bookmarks, that was successfully synchronized between two desktops are not synchronized with the phone. What is the right way to bring all my bookmarks from the desktops to the phone? I am using an old Asus model with Android 4. Thanks in advance.
