quick search for mobile di mat

When I started using Firefox, I was surprised there was no extension to search a page like in the Google mobile app. It was missing an add-on that allowed you to make a Bing search from a text selection without opening a new tab.
I developed this code primarily for personal use, so there may be some bugs or display issues. If you encounter any problems or have feedback, feel free to email me here.

Contributions and suggestions for improvements are welcome. :)

The language of this add-on adapts to your browser's language for search results.
