<p>There are a couple of differences between desktop Firefox and Firefox for Android that are particularly relevant to add-on developers:</p>

<ul>
 <li>there is no visible XUL in the user interface, so you can't use XUL overlays to create your add-on's UI</li>
 <li>the <a href="https://developer.mozilla.org/en-US/docs/Code_snippets/Tabbed_browser" title="https://developer.mozilla.org/en-US/docs/Code_snippets/Tabbed_browser"><code>gBrowser</code></a> object does not exist, so you can't use <a href="https://developer.mozilla.org/en-US/docs/XUL/tabbrowser" title="https://developer.mozilla.org/en-US/docs/XUL/tabbrowser"><code>tabbrowser</code></a> to interact with browser tabs</li>
</ul>

<p>Instead, Firefox for Android provides its own APIs:</p>

<ul>
 <li><a href="/en-US/docs/Extensions/Mobile/API/NativeWindow" title="/en-US/docs/DOM/en/Extensions/Mobile/API/NativeWindow"><code>NativeWindow</code></a> enables you to manipulate parts of the native Android UI</li>
 <li><a href="/en-US/docs/Extensions/Mobile/API/BrowserApp" title="/en-US/docs/Extensions/Mobile/API/BrowserApp"><code>BrowserApp</code></a> enables you to interact with browser tabs</li>
 <li><a href="/en-US/Add-ons/Firefox_for_Android/API/PageActions.jsm">PageActions.jsm</a> allows you to add buttons to the urlbar. {{fx_minversion_inline("34")}}</li>
 <li><a href="/en-US/docs/Extensions/Mobile/API/Prompt.jsm" title="/en-US/docs/Extensions/Mobile/API/Prompt.jsm"><code>Prompt.jsm</code></a> allows you to easily show native prompts, dialogs, menus, and lists</li>
 <li><a href="/en-US/docs/Extensions/Mobile/API/Notifications.jsm"><code>Notifications.jsm</code></a> allows you to handle system notifcations</li>
 <li><a href="/en-US/docs/Extensions/Mobile/API/Home.jsm" title="/en-US/docs/Extensions/Mobile/API/Prompt.jsm"><code>Home.jsm</code></a> allows you to customize the home page</li>
 <li><a href="/en-US/Add-ons/Firefox_for_Android/API/HomeProvider.jsm" title="/en-US/docs/Extensions/Mobile/API/Prompt.jsm"><code>HomeProvider.jsm</code></a> allows you to store data to show on the home page</li>
 <li><a href="/en-US/Add-ons/Firefox_for_Android/API/Accounts.jsm" title="/en-US/docs/Extensions/Mobile/API/Prompt.jsm"><code>Accounts.jsm</code></a> allows you to start the Firefox Account set-up process</li>
 <li><a href="/en-US/Add-ons/Firefox_for_Android/API/JavaAddonManager.jsm" title="/en-US/docs/Extensions/Mobile/API/Prompt.jsm"><code>JavaAddonManager.jsm</code></a> allows you to dynamically load and interface with compiled Java code. {{fx_minversion_inline("42")}}</li>
 <li><code><a href="/en-US/docs/Mozilla/Add-ons/Firefox_for_Android/API/Snackbars.jsm">Snackbars.jsm</a></code> allows you to show Snackbar notification.&nbsp; {{fx_minversion_inline("44")}}</li>
</ul>

<p>In these pages we've documented the main functions and properties exposed by these objects. To see all the details, refer to the code at <a class="external" href="https://mxr.mozilla.org/mozilla-central/source/mobile/android/chrome/content/browser.js" title="https://mxr.mozilla.org/mozilla-central/source/mobile/android/chrome/content/browser.js"><code>browser.js</code></a>.</p>

<p>We also have some modules that don't ship with Firefox for Android but can be used in addons:</p>

<ul>
 <li>
  <p><code><a href="/en-US/docs/Mozilla/Add-ons/Firefox_for_Android/API/Sound.jsm">Sound.jsm</a></code> lets you play sounds in the browser simply</p>
