My windows 7 crashed. I was running latest FF for Windows 7. I was able to recover the AppData folder from FF. But I had to install Windows 10.
On Windows 10, I installed latest firefox. Created a 2nd account “Asus”. After creating the account, I deleted the contents of the created profile and put the one from the Windows 7 account.
I launched FF from Windows+R with the following
firefox.exe -PAsus -no-remote
Firefox opened and unlike my before, I now can go to my bookmarks where I have the option to do a restore. When I attempt to do a restore, I get an error:
“Unable to process the backup file.”
I have delete the places.sqlite file. I have made sure that my files and the folder are not read-only. But I continue to get the same error.
