Want to create your own Firefox search plugin? The steps on how to do this used to be a lot easier back in the early days of Firefox, but now with the OpenSearch protocol in all modern browsers – the steps are a little more difficult. Have no fear though, because I have found a resource that will make creating your own Firefox search plugin easy again and it takes only a few simple steps.
The first thing you will want to do is point your browser towards the OpenSearch plugin generator. This awesome utility allows you to create a search plugin in he open search format that Firefox (and many other browsers) use. This way you could search Firefox Facts without even visiting the website first and typing your search into my search form. The only hard part about this is locating the HTML source code that represents the search box on the website. In Firefox, you can do this fairly easily by right-clicking on a website, choose "View Source" and then find where the form starts for the search box.
Here is one more quick tip, if you hit "Ctrl + F" you can bring up the search options in the webpage’s view source pane. From there, search for "form" until you find the right form you need. For webmasters, this should be pretty easy. Now, for the easy part.
On the OpenSearch plugin generator webpage, simply fill in the website name, the website URL and then copy and paste in the form data you found on the website you want to create the search plugin for. I would recommend not changing the data for input encoding, plugin file name, or favicon file name. Next, hit the big button labeled "Generate Plugin".
The website will now give you the code you need to save on your own website hosting server to make the search plugin work. Scroll down the webpage, and make sure you follow each step as they have it. Once you are done, you too can have your own search plugin like this:
Hope this helps you create a search plugin for your own website. If you do create one using this method, be sure to share it in the comments!
