After updating to ff 5.0 I can't sign my bills at the bank site. It's OK to log in using my certificate. I can fulfill in all data but when I try to sign with the same security certificate on the card as with log in it doesn't work. It worked before with ff 4.x and it works with IE from MS. It's pity that I must go back to it. I tried to allow cookies and trust the site but it is already done and do not help. Please lead me to the solution.
