Notes 
xBrowserSync is a Chrome extension that enables you to synchronize your browsing sessions across multiple browsers and computers. This means that you can start browsing on one device, then continue on another without losing your current session.

Hardened
A hardened pick. Worth the effort once you have chosen to shrink your footprint on purpose. Enough for most people. Threat levels
Our take
xBrowserSync syncs bookmarks and tabs across browsers and devices while encrypting your data client-side, so you can ditch a Google or Mozilla account for sync and keep the convenience. It is a narrow tool, not a privacy suite, and you are trusting either a community server or one you self-host for availability. Worth it for people who want cross-browser sync without handing the bookmark list to a big vendor, and who do not mind the slightly fiddly setup.
