C:\Windows.old\Users\your-user-name\

The usual kind of Reset in recent versions of Windows retains your old user folder, but moves it here: C:\Windows.old\Users\''your-user-name''\ Can you find that folder? If so, your Firefox data probably is in there -- and here is how I suggest accessing it: First, it would be helpful to set Windows to show hidden files and folders. This article has the steps: http://windows.microsoft.com/en-us/windows/show-hidden-files Then click into: C:\Windows.old\Users\''username''\AppData\Roaming\Mozilla\Firefox\Profiles ''Note: you might find a cache folder under AppData\Local, but all the important stuff is under AppData\Roaming.'' Here you may find one or more semi-randomly named folders. The one with the most recently updated contents probably is the one you want to restore from. '''''Bookmarks Only''''' Drill down into the old '''bookmarkbackups''' folder and copy the two most recent backups to a convenient location such as the desktop. The Restore feature will replace the default Firefox bookmarks (and anything you just added since the Reset) with the older set of bookmarks. If you need to preserve newly added bookmarks, use the export feature first, before the Restore, and then the Import feature afterwards. The following articles have the details: * (Optional) [[Export Firefox bookmarks to an HTML file to back up or transfer bookmarks]] * [[Restore bookmarks from backup or move them to another computer]] -- to access the backups on the desktop, use the "Choose file" command on the menu * (Optional) [[Import Bookmarks from an HTML file]] Success? '''''Complete Restoration''''' This post has my suggested procedure for resurrecting your entire old profile in your new installation of Firefox. Please note the use of ''copy'' instead of ''move'' throughout the process. This allows you to try again if it fails somewhere along the way. https://support.mozilla.org/questions/1024189#answer-638319 Any luck?
