I just made a post asking for help figuring out how to put my Yahoo toolbar back on my browser. But after I posted it, I went and looked online and found out what I was doing wrong.
When I downloaded MSN messenger, it got rid of my Yahoo toolbar. The instructions said to go to tools, then manage add-ons, then add or delete add-ons. It showed that my Yahoo toolbar was enabled. That didn't work to solve my problem. What I finally found was that on the browser, there is a "view" button. It has a feature to show or hide toolbars. I clicked on show Yahoo toolbar and up it popped. I just thought I would put this out there in case anyone else has had a problem like this.
