I have a Windows 10 desktop PC, a Samsung Galaxy Tab A android tablet, and a Samsung Galaxy A10E phone. I am using Firefox 94 on all these devices. I am trying to sync my Firefox bookmark from my PC to my tablet and my phone. I tried to sync last night and left all my devices on all night, and this morning, there were no bookmarks on my tablet or my phone. When I select bookmarks on my tablet or phone, all I am getting is a little black circle which keeps spinning. How do I get my bookmarks from my pc to my tablet and my phone?
