I use Firefox pretty much as my exclusive browser and my e-mail address book got hijacked and it has been sending out many MANY e-mails to all the connections I have. I changed my password yesterday evening and have responded to any one that writes me to tell me of the issue. On the good side the Mailer Demon has sent back addresses that are no longer valid, but it was so many I was not able to keep track of them and make the changes.
