Search

This document describes the implementation of parts of Firefox’s search interfaces.

The search area covers:

• Search bar on the toolbar

• In-content search

• One-off search buttons on both the search and address bars

Search Engine handling is taken care of with the toolkit Search Service.

Most of the search code lives in browser/components/search.
