Regarding "About this Add-on" Puntuado con 4 de 5 estrellas
Actually my "review" applies to the extension's description here on addons.mozilla.org, specifically the text under "About this Add-on", where you will find this statement:
> Get the latest news about Xmarks at our blog: http://blog.xmarks.com/
The last entry at the linked blog dates from Monday, December 17, 2012 and regards an "upcoming" (sic) outage of xmarks.com for scheduled maintenance. That news is not recent, and the outage is obviously no longer upcoming.
If the blog is no longer the best place to look for recent news about Xmarks, what has replaced it in that role?
