On Nov 14, my Lenovo laptop received a notice from Microsoft that it was updating Windows 10 and not to shut down the laptop. After an hour or so, I checked my laptop which had only a blank screen. My Office 365 was missing as was all of my Mozilla/Firefox files (folders and bookmarks) that have been in use for the past 10+ years were missing, no where to be found for re-installing. Mozilla & firefox are used for both personal and business, but primarily for business My 2 Gmail addresses gave been reestablished as well as the saved emails in each. However the hundreds of folders and bookmarks are still missing, and efforts to down load them to restore them to my laptop have not been successful. Even though MS created the problem with their latest Windows 10 update, they are unable or not allowed to work on 3rd party software or applications I would greatly appreciate any information that would facilitate restoring these very important (to me) folders and bookmarks. Please send you tech support and /or advice on restoring these files to my email. Tom R.
