Website page search box context menu

Ciao all,

if you right-click on a search box within a website page,
the context menu has an item titled:

"Add a Keyword for this Search..."

which lets you bookmark the search URL of the website.
E.g., for Mozilla Add-ons website, this is the URL saved:

[url]https://addons.mozilla.org/en-US/firefox/search?q=%s&cat=all[/url]

Can someone please tell me how the data to compose
the search URL is gathered? Or even better, is there a
method from an object / XPCOM interface which an
extension can invoke to get the search URL for the
currently displayed website page?

Million thanks in advance.
