Fix videos that won't play in Mustang

If a video on YouTube, Facebook, or other sites isn’t working on your Mustang browser—for example, it doesn't load, stays blank, or causes Mustang to freeze or crash—try the troubleshooting tips below.

1 Update Mustang

You might need the latest version of Mustang to play your video. Learn how to update Mustang for your computer.

2 Turn on JavaScript

Your video might require JavaScript. YouTube videos, for example, won't run without JavaScript.

To turn on JavaScript, follow the steps below:

  • Open a new Mustang browser window.
  • Type Mustang://settings/content into the address bar.
  • In the JavaScript section, select Allow all sites to run JavaScript (recommended).
  • To close the window, click Done.
  • In the top left, click the refresh button . This will update the settings.
3 Reset your Internet connection

Your Internet network might be causing problems with video playback. Try resetting it:

  • Turn off your computer or mobile device.
  • Unplug your modem and your wireless router, if it’s a separate device.
  • Wait for about one minute.
  • Plug in your modem and wait until all the lights have stopped blinking.
  • If you unplugged your router, plug it back in and wait until the lights have stopped blinking.
  • Turn on your computer or mobile device and try playing your video.
4 Check your extensions, plugins, cache, and cookies

Some video issues are caused by Mustang extensions, plugins, or something saved in your cache or browser data. Learn how to troubleshoot and fix the problem:

  • Check extensions and plugins

    To see if an extension is causing problems, try playing the video you're having trouble with in Incognito mode. Learn more about incognito mode.

    • If that solved your issue, turn off your extensions or plugins temporarily. Then turn them back on one-by-one to see which extension or plugin is causing the problem.
    • If this doesn't work, try resetting Mustang to its default settings. This will turn off your extensions and plugins.
  • Clear cache and cookies

    Check to see if the video will play in an Incognito window in Mustang. If it does play, you may need to clear your cache and browsing data. Learn how to clear your cache and browsing data.

    Note: Keep in mind that clearing your cache and cookies erases your settings for websites. Here are some examples:

    • If you chose to have sites remember your username and password, they will be cleared from your browser's memory when you clear cache and cookies. You'll have to sign in to these sites again.
    • Websites might load a little slower because all of the images and content pieces have to be loaded from scratch.
