I’ve been working with Magento for some time now. I found myself searching for help countless times on the Magento website. I thought it would be useful to have a search feature built right into Firefox’s list of search engines to search the Magento site. So I went through Mozilla’s Developer Center and found instructions on the Open Search Syntax. So here you go, you can download it here. Hope you find it helpful!

I also have one for PHP which comes in handy as well. If your interested, you can grab it here.
