A note popped up yesterday asking me if Mozilla Thunderbird could update my program, and I said yes. Now when I'm addressing emails the contact doesn't quickly pop up--I have to type very slowly and if I go too fast it just won't complete the addressing. And the contact field and subject field have all turned blue when they used to be white. I can't tell if this is malware or a bad update, but I'd like to go back to where when I start typing in a name the contact email address quickly comes up! Thanks, Marsha
