This page lists APIs that only run in Gecko Chrome code (and sometimes in other privileged circumstances.)
Note: Most of the APIs exposed to the Web in general are also usable in Chrome code: see Web APIs for a list of these.
- Browser API
- The HTML Browser API is an extension of the HTML
<iframe>
element that allows web apps to implement browsers or browser-like applications. It currently works in (privileged) chrome code on Firefox desktop (version 47 and above) and privileged and certified apps on B2G/Firefox OS.
