 In the following figure,
 the multicolored square
 to the right of the address bar
 is the icon for a browser action.
 A popup is below the icon.

 If you only provide one of the 19px or 38px icon size, the extension system will
 scale the icon you provide to the pixel density of the user's display, which
 can lose detail or make it look fuzzy. The old syntax for registering the
 default icon is still supported:

 <p>Browser action icons can be up to 19 dips (device-independent pixels)
   wide and high. Larger icons are resized to fit, but for best results,
   use a 19-dip square icon.</p>
 
 <p>You can set the icon in two ways:
   using a static image or using the

+  HTML5 <a href="http://www.whatwg.org/specs/web-apps/current-work/multipage/the-canvas-element">canvas element</a>.
   Using static images is easier for simple applications,
   but you can create more dynamic UIs &mdash;
   such as smooth animation &mdash;
   using the canvas element.
   </p>
 
 <p>Static images can be in any format WebKit can display,
   including BMP, GIF, ICO, JPEG, or PNG.
   For unpacked extensions, images must be in the PNG format.

 To set the tooltip,
 use the <b>default_title</b> field of <b>browser_action</b>
 in the <a href="#manifest">manifest</a>,
 or call the $(ref:browserAction.setTitle) method.

 <h3 id="badge">Badge</h3>
 
 <p>Browser actions can optionally display a <em>badge</em> &mdash;
   a bit of text that is layered over the icon.
   Badges make it easy to update the browser action
   to display a small amount of information
   about the state of the extension.</p>

 <h2 id="tips">Tips</h2>
 
 <p>For the best visual impact,
   follow these guidelines:</p>
 
 <ul>
   <li><b>Do</b> use browser actions for features
     that make sense on most pages.
   <li><b>Don't</b> use browser actions for features
     that make sense for only a few pages.
-    Use <a href="pageAction.html">page actions</a> instead.
+    Use <a href="pageAction">page actions</a> instead.
   <li><b>Do</b> use big, colorful icons that make the most of
     the 19x19-pixel space.
     Browser action icons should seem a little bigger
     and heavier than page action icons.
   <li><b>Don't</b> attempt to mimic
     Google Chrome's monochrome menu icon.
     That doesn't work well with themes, and anyway,
     extensions should stand out a little.
   <li><b>Do</b> use alpha transparency
     to add soft edges to your icon.
     Because many people use themes,
     your icon should look nice
     on a variety of background colors.
   <li><b>Don't</b> constantly animate your icon.
     That's just annoying.
 </ul>
