How to Add Your Own Application to the New Yahoo Toolbar (Firefox)

Yahoo Toolbar is a browser extension for Firefox that allows users to access Yahoo services such as Yahoo Mail, Yahoo Search, and Yahoo News directly from their browser. If you want to add your own application to the Yahoo Toolbar, you can follow these steps:

1. Create an icon for your application. The icon should be 16x16 pixels in size and saved in either .ico or .png format.

2. Create an XML file that describes your application. This file should include the name of your application, the URL to launch it, and the location of the icon file you created in step 1. Here is an example of what your XML file might look like:

``` <?xml version="1.0" encoding="UTF-8"?> <OpenSearchDescription xmlns="http://a9.com/-/spec/opensearch/1.1/">

 <ShortName>My Application</ShortName>
 <Description>Launch My Application</Description>
 <Url type="text/html" method="get" template="http://myapplication.com"/>
 <Image height="16" width="16" type="image/png">http://myapplication.com/myicon.png</Image>

</OpenSearchDescription> ```

3. Upload your XML file and icon file to your web server.

4. Open Firefox and click on the Yahoo Toolbar icon in the top right corner.

5. Click on the gear icon in the toolbar and select "Add Content".

6. Click on "Add Custom Content" and enter the URL to your XML file.

7. Click "Add" and your application should now be added to the Yahoo Toolbar.

Note that Yahoo may require you to register your application and obtain an API key before you can add it to the toolbar. You should check their developer documentation for more information.
