Firefox and Thunderbird address line blacked out

by isumbras - 2/7/12 6:41 AM

When entering a recipient in the To, Cc, or Bcc field the line is blacked out and the recipient's address is blacked out. The same problem occurs in Firefox when entering a URL into the URL field.
MacBook Pro
OS X 10.7
Latest versions of Firefox and Thunderbird

Many thanks to any-one who can help.
