That's all great but neither this nor www.xbrowsersync.org supports Safari.
That's the reason I don't use Safari beyond random superficial browsing.
Here is what xBrowserSync has to say about it:
"Will xBrowserSync support Safari?
No and it is extremely unlikely this will ever happen due to Apple moving away from the WebExtensions API and forcing developers to purchase Apple hardware and pay $99/year to develop on their platform."
