1//! This example changes the current text in Firefox's browser search bar from 
2//! "Old search text" to "New search text". To run this example, open an instance
3//! of Firefox and type "Old search text" in the search bar. If all goes well, when
4//! you run this example as root, it should be replaced with "New search text",
5//! although you may have to click on the search bar again in order for it to
6//! render the new text.
