<p>Your extension may optionally also supply an associated popup whose content is specified using HTML, CSS, and JavaScript.</p> <p>You must specify this key to include a page action in your extension. When specified, you can manipulate the button programmatically using the <a href="/en-US/docs/Mozilla/Add-ons/WebExtensions/API/pageAction"><code>pageAction</code></a> API.</p> <p>If you supply a popup, then the popup is opened when the user clicks the icon, and your JavaScript running in the popup can handle the user's interaction with it. If you don't supply a popup, then a click event is dispatched to your extension's <a href="/en-US/docs/Mozilla/Add-ons/WebExtensions/Anatomy_of_a_WebExtension#background_pages">background scripts</a> when the user clicks the icon.</p> <p>Page actions are like browser actions, except that they are associated with particular web pages rather than with the browser as a whole. If an action is only relevant on certain pages, then you should use a page action and display it only on relevant pages. If an action is relevant to all pages or to the browser itself, use a browser action.</p> <p>While browser actions are displayed by default, page actions are hidden by default. They can be shown for a particular tab by calling <a href="/en-US/docs/Mozilla/Add-ons/WebExtensions/API/pageAction/show"><code>pageAction.show()</code></a>, passing in the tab's <code>id</code>.

inside the browser's URL bar.</p>\n<p>Your extension may optionally also supply an associated popup whose content is specified using HTML, CSS, and JavaScript.</p>\n<p>You must specify this key to include a page action in your extension. When specified, you can manipulate the button programmatically using the <a href=\"/en-US/docs/Mozilla/Add-ons/WebExtensions/API/pageAction\"><code>pageAction</code></a> API.</p>\n<p>If you supply a popup, then the popup is opened when the user clicks the icon, and your JavaScript running in the popup can handle the user's interaction with it. If you don't supply a popup, then a click event is dispatched to your extension's <a href=\"/en-US/docs/Mozilla/Add-ons/WebExtensions/Anatomy_of_a_WebExtension#background_pages\">background scripts</a> when the user clicks the icon.</p>\n<p>Page actions are like browser actions, except that they are associated with particular web pages rather than with the browser as a whole. If an action is only relevant on certain pages, then you should use a page action and display it only on relevant pages. If an action is relevant to all pages or to the browser itself, use a browser action.</p>\n<p>While browser actions are displayed by default, page actions are hidden by default. They can be shown for a particular tab by calling <a href=\"/en-US/docs/Mozilla/Add-ons/WebExtensions/API/pageAction/show\"><code>pageAction.show()</code></a>, passing in the tab's <code>id</code>. You can also change this default behavior using the <code>show_matches</code> property.</p>"}},{"type":"prose","value":{"id":"syntax","title":"Syntax","isH3":false,"content":"<p>The <code>page_action</code> key is an object that may have any of three properties, all optional:</p>\n<figure class=\"table-container\"><table class=\"fullwidth-table standard-table\">\n <thead>\n <tr>\n <th scope=\"col\">Name</th>\n <th scope=\"col\">Type</th>\n <th scope=\"col\">Description</th>\n </tr>\n </thead>\n <tbody>\n <tr>\n <td><code><a href=\"/en-US/docs/Mozilla/Add-ons/WebExtensions/user_interface/Browser_styles\">browser_style</a></code><br><span class=\"badge inline optional\">Optional</span><br><abbr class=\"icon icon-deprecated\" title=\"Deprecated.
