I'm glad to have it, but

  • addons' settings are not part of it
  • bookmarks order gets jumbled
  • compared to Safari and iCloud, sync is a bit on the slow side if not significantly delayed in the sync between desktop and iOS.

It encrypts all your data end-to-end without you needing to do anything (it uses your Mozilla account password.). Also, it sends you mails you need to verify (click) when a new device is added to your account as an additional security precaution when you sign-in into a new device.

Apart from that great security, it's really easy to use, syncs all your tabs, history, add-ons, passwords, bookmarks etc. across all devices (even Android), so you can use them everywhere. You can also send a tab to a different Firefox/device.

Fortunately content is encrypted on your device prior to uploading. This is better than the contrary and better than "services" which create the key for "your convenience"

If the data can be retrieved under subpoena it is NOT SECURE.

Very good comparison (1) of cross-browser-bookmark-synchronization-services : It seems, that Xmarks (2) has no real competitor concerning the cross-browser-bookmark-synchronization-abilities. No other bookmark-sync-service than Xmarks is able to sync Bookmarks (and passwords) across IE, FF, Chrome, Mac OS X10, iPhone and iPad. Additionally you quickly can share a Xmarks-folder (with subfolders) with your personal internet-bookmarks online as webpage and you can vote and see the average voting of other Xmarks-users for the quality of sites. Further as an alternative to the Xmarks server you can use your own server for your bookmarks, and you also can sync the passwords across all your used browsers and computers, if you want. Bookmark.com (3) has no Chrome-support and a bad reputation on (4), whereas the reputation of Xmarks is excellent on (5) nearly equal to the excellent reputation of AlternativeTo.net, see (6).

this is just one of many reasons, Xmarks will be shutting down its services.

Tried both Weave as XMarks, and Mozilla won me with their easy, clean and simple setup. Pro for XMarks is that it works throughout multiple browsers where Weave is Mozilla browsers only. Since I work Firefox-only the easy and full featured sync of Weave beats XMarks hands down for me nonetheless.
