I have Firefox sync set up and I've confirmed it is syncing properly. I have a bookmark on the bookmarks toolbar that I have been using since I first set up the sync account to let me see tabs from my other synced devices. However, as of Firefox 55 this bookmark no longer works and I can't seem to find what has replaced it. The URL is about:sync-tabs and before Firefox 55 it showed the list of devices and the synced tabs underneath each device name. Now it just says invalid URL.

You can open the tabs from other devices in the sidebar.

  • View -> Sidebar -> Synced Tabs

You can tap the Alt key or press the F10 key to show the hidden Menu Bar temporarily

Yup, that way still works. Having them on the bookmarks toolbar was a lot faster easier though since I don't really leave the sidebar open. Guessing that means about:sync-tabs was deprecated?
