firefox sync has worked pretty great for me, across all devices. I don't self host it, but seems like once again, they've gotten it to the point where you can.
Works great, go to sign in to sync, create a firefox account. login on all your devices, bookmarks show up, you can send tabs to other devices, you can see open tabs on other devices. Password Managers works great also, just set a master password to lock passwords
Yeah with the official servers. I was talking about the self-hosted version of sync.
I would love a self hosted version that I could just point my Firefox to, with actual logs and a way to verify it's working besides tabs appearing on other devices.
