-### The video controls are not showing up?
-
-This extension is only compatible
+**The video controls are not showing up?** This extension is only compatible
 with HTML5 video. If you don't see the controls showing up, chances are you are
 viewing a Flash video. If you want to confirm, try right-clicking on the video
 and inspect the menu: if it mentions flash, then that's the issue. That said,
 most sites will fallback to HTML5 if they detect that Flash is not available.
 You can try manually disabling Flash from the browser.
