Tor Browser 4.0 (Windows) unable to import new CA certificates from file
Attempting to import a new CA certificate from a .CER file fails.
The script console reports NS_ERROR_FAILURE: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIX509CertDB.importCertsFromFile] certManager.js:510
Regression from Tor Browser Bundle 3.6.6 and all prior versions (which imported the same cert without error).
Firefox 34.0 has no problem importing the CA certificate either.
