I have updated to the latest versions of Firefox and the latest/new version of Firefox Sync on both my devices by following the instructions from this support site. QUESTION: Did disconnecting my devices from the old sync mechanism delete any and all of my information (e.g. bookmarks, passwords, etc.) from Mozilla's servers? QUESTION: If disconnecting my devices from the old sync mechanism did NOT delete all of this information from the Mozilla's servers, how do I now delete all of that information from the old sync mechanism? Also, if it did not and a step was required to do so before disconnecting my devices, that should be added to the instructions about moving to the new sync. This seems to have been asked in a couple of different threads, but the answers I read all seem to describe how to either upgrade to the new sync mechanism or delete an account from the new sync mechanism. One provided a link to a site to delete an account, but it's unclear if that will delete the account from the old sync mechanism or from the new sync mechanism since there's no indication as to which is which in Mozilla's account services. Thanks for your help!
