… as the title suggests. It would be super handy to have.
Even Jolla could implement its own synchronization instance https://github.com/mozilla-services/syncserver
AFAI understand the firefox instance is pretty much safe since the data are encrypted decrypted on the device. So i don’t see a need for Jolla to run its own.
The firefox instance?
The server or whatever firefox uses to sync.
I think the OPs request was about support for using it in the browser. Like in the firefox browser. I rely on it a lot syncing with 3 devices. Just the other day my Firefox settings got corrupted on my laptop, and all I had to do was to sync instead of using endless time trying to remember all settings, plugins, bookmarks etc.
Do you know that everyone can run a Firefox Sync server? The magic of Opensource software.
That’s what Juanro49 suggested, as an addition to what OP requested, not a solution.
Personally I think it would be great if Jolla ran its own, but I don’t know how that would jibe with people’s existing sync profiles.
