Make a Firefox search Add-on for a GCSE

Adding an search engine to Firefox is the only disadvantage to Firefox. You have to install an add-on. Compare that to Opera, where you can right click the search field. To make things worse, search add-ons are in XML. I could go on and on, but I will put my dialog at the end and you may read it if you like.
TO make this search addon your GCSE will have to follow this tutorial:http://sethsdiscoveries.blogspot.com/2012/10/two-page-more-customizable-gcse-for.html
Open notepad and enter this code:

<OpenSearchDescription xmlns="http://a9.com/-/spec/opensearch/1.1/">

Seth's Tutorials is the name of the add-on and the name of the search engine displayed in the search box.   Search for code and PC tutorials by Seth Sevenyoln is the description which is displayed in the search results of Mozilla add-ons directory.  http://sethsdiscoveries.blogspot.com/favicon.ico  is the URL of the icon and no it doesn't work for me either. http://sethsdiscoveries.blogspot.com/p/search-results.html?q=  is the URL where results are displayed. For example, if you wanted to search fireburst.webs.com the URL would be fireburst.webs.com/searchresults.htm?q=. A way to find this out is to search for "n" and take the "n" out of the URL. http://sethsdiscoveries.blogspot.com  is the URL of your homepage. Mine looked like this:

Then save it as "searchname.xml" To save it as an xml file you will need to put the filename in quotations. Mine looked like this:

Open Firefox and navigate to addons.mozilla.org. Log in or sign up with a developers account(free). Follow the steps and submit your addon. You're finished. You can download the add-on for my blog here
