Today Firefox suggested to do "refresh", said it would not effect bookmarks, but when did it, wiped out all my bookmarks. Followed directions in support posts - under "Import and Backup", "Restore", selected latest date, Ok to replace, and then get "Unable to process the backup file". An old gray beard with limited computer skills requests help.

These can't get your data back, but will help in the future.

These add-ons can be a great help by backing up and restoring Firefox

FEBE (Firefox Environment Backup Extension) {web link} FEBE allows you to quickly and easily backup your Firefox extensions, history, passwords, and more. In fact, it goes beyond just backing up -- It will actually rebuild your saved files individually into installable .xpi files. It will also make backups of files that you choose.
