Hi Gary

Do you see your user name or email address in the Firefox for Android menu? Select this to access the Firefox Sync settings.

I hope that this helps.

Thanks. But I am signed in. But the needed Sync line is just not there, not on my phone nor on either of my tablets.

Are you able to share a screenshot of the open Firefox for Android menu?

Here are two screen shots showing the entire Settings menu. As you can see, there is no "sync" line.
