Non-standard use of search plugins

We all love to watch videos on YouTube, LoadUp and other video services which have proliferated on the Internet a certain number over the past few years. Sometimes you want to save a particularly liked video for later viewing offline. To save videos, there are also services that are slightly smaller than video content services. Once upon a time, my choice fell on 0Download.ru . Now I will tell you how to use the firelight search plugin system to quickly download videos using the example of the 0Download service.
So, for a successful download, we need:

Ognelis v2.x.
Expansion "OpenSearchFox".
What a movie, for example from YouTube located in a blog, for example, the beloved Habr. ;)
We download and install Ognelis (if he suddenly, for some reason unknown to me, you have not yet installed).
Install OpenSearchFox.
Go to the 0Download home page (or your favorite service to download the video), right-click the rodent click on the input field in which you need to enter the video URL, select "Add Open Search plugin".


')
Enter the name of the search engine and its description.



Go to the page with the clip and copy its URL to the clipboard.



We select our favorite video download service from the list of search engines and paste from the clipboard a copied string with a clip.



Hit Enter and get the page with a link to the video ...



It was such a non-standard way of using a search engine that somehow came to my head and fully confirmed my performance. I would like to know from the respected habra people, maybe you have examples of non-standard use of standard features?
