Cannot import certificates in Ubuntu 12.04
I've been using certificates in Firefox for several years. Now they are no longer in Firefox, and I cannot import them, neither authorities or personal. When I import a *.cer certificate (authority) nothing happens. When trying to import a personal certificate (*.p12, or *.pfx), after entering password, an error occurs: "The PKCS #12 operation failed for unknown reasons." What can I do? Thank you very much.
