Obrigado! Glad you are happy with xBrowserSync!

It depends on the service you use to sync to, the default service (api.xbrowsersync.org) has an inactivity period of 21 days. You only need to be concerned if Firefox is not opened or the xBrowserSync extension is disabled for periods of time approaching 21 days, otherwise you don't need to be concerned about your sync data being removed.

Many thanks Jimi! If you'd like to raise a feature request please do so here: https://github.com/xbrowsersync/app/issues

Hi there, I'm really sorry for the issues yourself and others have had. This is due to bugs in the syncing code, as well as a bug in Firefox's bookmarks API.

I've been working hard to get all of these syncing issues resolved and have now fixed the known issues in dev, the upcoming v1.5.0 release will include these fixes. Firefox v69 resolves the bookmarks API issues which I've tested in Nightly and confirmed.

v1.5.0 with Firefox Nightly should resolve all syncing issues so please bear with me. Thanks for your understanding!!
