I'm trying to check my email in Yahoo, and a message pops up saying that my browser isn't updated. I'm using Internet Explorer.
You can try a couple of things. If you Google "update internet explorer" you will see as the first option a link (copied below) to upgrade to the newest version. Please note you must be running Windows Vista or Windows 7.
If you have Firefox downloaded, you can just try using that. If not, you can Google "firefox download" and go to their site to start the free download process. I included that link below, as well.
