Favorites and settings.
Your favorites, search engine, blocking state and exceptions, home page, and theme, encrypted on your device before upload.
Your favorites and settings on your other devices, and, if you choose, your open tabs.
Turn on sync once per device with a sync name and passphrase. Favorites and settings follow you. Flip one more switch and each machine also publishes what it has open, to browse from the island, the Quick Switcher, or the start page.
Favorites and settings. Open tabs if you choose.
Open tabs, per device.
Off until you turn it on. Each machine publishes its own open tabs; nothing merges or rearranges.
Never synced.
History, downloads, permissions, cookies, site data, and private tabs stay on the device.
Reading another device never rearranges it.
Off until you say so, on each device.
Sharing is a per-device switch in Settings, off by default. A machine’s tabs never leave it until you flip the switch on that machine — and flipping it off withdraws them.
Open here, not there.
Another device’s tabs are a read-only list. Picking one opens it as a fresh local tab; nothing force-opens, closes, or reorders on the other side.
Sync belongs to Personal.
Sync is available only to Personal. Named local profiles and independent windows let you separate browsing identities on this device.
Everywhere you already look.
Remote tabs sit behind a folded section in the island panel, match in the Quick Switcher below your local tabs, and appear on the start page under “on your other devices.”
