I am having the same problem as in this ticket, but the solution doesnt work for me:<br /> https://support.mozilla.org/questions/947476 Firefox -> Prefrences -> Advanced -> Certificates -> View certificates -> import Select the cert, enter password, then i get this message: <br /> Successfully restored your security certificate(s) and private key(s). However the cert does not show up on my cert list, and i cannot access the site that requires this cert. I am using Mac OSX 10.6.8 and Firefox 29. I do know that the certificate itself works because i can use it on another machine. I tried deleting both CERT8.db and SECMOD.db with no success. I hope someone knows how to fix this because i need to file my taxes!!!! Thanks in advance
