Just changed desktop devices. When I opened Mozilla/Firefox with my account password and installed it,my bookmarks disappeared. How do I get them back?

Your bookmarks showed up after you connected to your account but now they are gone, or Sync didn't bring them over at all?

You can check what data is in the Sync cloud for your Mozilla Account using the About Sync add-on:

https://addons.mozilla.org/firefox/addon/about-sync/

After you install the add-on, you can type or paste about:sync in the address bar and press Enter to load it. The page shows each category of data currently found in the Sync cloud.

Anything there under bookmarks?
