Just completed "Clean" overwrite install of Windows 10. Forgot to export/save Mozilla bookmarks. Any way to retrieve the bookmarks from the Windows.old (or Windows.000) file created during clean/overwrite install of Windows 10? I did retrieve a folder containing about 20 files all with similar name structure.

  Here is one example: "bookmarks-2018-03-19_502_O1cfqR3ir0OALnytM984gQ=="     with a JSONLZ4 extension.

Sometimes user data/files are saved.

Open your file browser to c:\ Then search for 'bookmarks-'

Allow the search to finish as there may be several such files. Once the search is done, look for any files like; bookmarks-2018-03-19_502_O1cfqR3ir0OALnytM984gQ==
