    Are you receiving a reminder form Yahoo to upgrade your Opera every time you login to Yahoo Mail?

    First, try going to this link and installing the latest version of Opera:

    Download Opera for computers - Opera Software

    If that does not work, to fix this problem you'll need to trick Yahoo Mail into thinking that your Opera is Firefox.

    To change your User Agent and make Yahoo think you're using Firefox download and install this plugin:

    Restart Opera, then change your user agent to Firefox:

    If Yahoo Mail thinks your Firefox is too old you'll need to update the Firefox user agent.

    Go to the Opera menu and select Extensions (or keyboard Control+Shift+E):

    Select the Firefox group and click Edit next to Firefox for Windows:

    Replace the string listed with:

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