Wouldn't it be cool if you could add search plugins for any search form to the Firefox Search Bar, instead of having to create the plugin yourself or wait for the site owner to stop being lazy and make one?
It's good that there's an extension for Firefox called Add to Search Bar that will add a new context menu item to let you create your own search plugins on the fly.
For instance, you can right-click on the search box here and then choose Add to Search Bar…
You'll be prompted to give it a name, I chose to shorten the site title down a bit.
And there we go, now I can search the How-To Geek from Firefox.
I've tested this on a number of sites, seems to work pretty well… at some point I'll stop being lazy and make an official search plugin.
