Can’t use Mozilla’s cert9.db with certutil.exe

Question

The following command: certutil.exe -L -d “C:\Users\Home\AppData\Roaming\Mozilla\Firefox\Profiles\1bku2z91.default-1633392324717\” returns this error message: certutil.exe: function failed: SEC_ERROR_LEGACY_DATABASE: The certificate/key database is in an old, unsupported format.

I tried with and without quotes, changed backslash to forward slash. I found comments that the destination folder has to include secmod.db, which my folder does not but I think this applied to cert8.db, not cert9.db. I am passing the right folder as per about:support lookup. My Firefox version is 66.0.3

Answer 1

you need to add "sql:" before the location of the folder to specify that is a sqlite db that you are trying to read so it would be:

certutil.exe -L -d sql:“C:\Users\Home\AppData\Roaming\Mozilla\Firefox\Profiles\1bku2z91.default-1633392324717\”
