    Type in a useful Description such as "Fix Yahoo Mail - Firefox 25" and then use this string in the User Agent line:

    Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:25.0) Gecko/20100101 Firefox/25.0

    Click OK to save the new user agent, then OK to close the user agent switcher options window.

    Now go to Tools, select Default User Agent, and Click the user agent you created in the previous steps:

    Open a new tab in your CometBird and go to

    As long as you are using the user agent created above you will not be prompted with the web browser upgrade notice.
