No, WinXP is the operating system - Firefox is a web browser, like Internet Explorer, aka IE.

If you are asking about getting rid of IE, the answer is no, too. First, it is so ingrained with the operating system you can't remove it completely without breaking the operating system; and second, some of you installed programs, like security applications, will use IE for getting updates.

Thank you so much & I'm loving Firefox. It only took a kazillion years to get on board but better late than never. Now, one other ?? I tried to send a card thru American Greetings but have been prompted to install Adobe Flash Player but it won't go thru normally nor won't manually either. Since I send out alot of cards & I upgraded to Firefox, I'm not prompted to upgrade but am unable to send out cards to mobile numbers unless I'm using Internet Explorer. Thanks again, Pam
