Firefox Sync which is built into firefox supports syncing of:
- Bookmarks
- Open Tabs
- Logins
- History
- Addons
- Preferences
You'll have to create a firefox sync account and install firefox on your mobile (available for ios and android).
In my experience you have to click the sync button manually on your desktop version of firefox (two clicks). Goto your phone and select "Your library" > Synchronised devices > swipe down to refresh. And you'll get all your open tabs.
I'm sure Firefox Sync's automatically but for me I found it too slow to update, so for the best experience I click the sync button on whatever device I'm using to switch between devices.
