Your Input Matters
The "YouTube without DASH Playback" extension turns off DASH support from HTML5 video element and hence causes YouTube (and other HTML5 video players) to fully load video files for offline access. Please note that one drawback of turning DASH support off is that some high quality options will be ignored by the HTML5 players. This is due to high memory requirement of these streams. Basically loading the entire video on high quality (like 1080p) requires too much memory that cannot be offered by Firefox for a single tab. There is no workaround for this. If for a particular video, high resolution is preferred, just use the toggle button to temporary enable DASH support.



  1. What is YouTube without DASH Playback extension and how does it work?

    YouTube without DASH Playback turns off DASH support from Firefox browser by disabling media.mediasource.enabled preference and hence HTML5 players behave as there is no support for media sources in this browser. This will result in fully loading of media sources. You can take advantage of this extension for watching video files offline. Simply turn the extension on by pressing the toolbar button. Now load or reload the video page and wait until the buffer is full. You can now disconnect from INTERNET and still watch the entire video.

  2. What's new in this version?

    Please check the Logs section.

  3. Can I always keep the extension enabled? Is this recommended?

    Well, it really depends on how use your browser. If you dont mind all media sources of all webpages being fully loaded, the answer is yes. However, if you care for how much the browser uses your bandwidth, it is recommended to toggle the extension on (disable DASH support) once you want to watch a video offline.

  4. If the extension is disabled, is it going to use my browser resources?

    Pretty much not. This extension is very light-weight. Meaning even if it is active, the only modification is does is to add the toolbar button. That's it. If you are not using it regularly it is recommended to move the toolbar button to the hidden panel as described in this blog post.

  5. Is YouTube without DASH Playback extension also working on other video websites?

    Yes as long as that particular website uses HTML5 player not Flash player.

  6. YouTube without DASH Playback extension doesn't seem to be able to stop DASH playback from a video site. How can I fix this?

    Make sure the website is using HTML5 player. If not you can force this by using extensions that mask Flash support from your browser by pretending Flash is not installed in your system.

  7. I like to keep the extension always active. How can I prevent YouTube tabs from start buffering videos as I like to selectively turn buffering on.

    I recommend you to install YouTbue No Buffer extension by "James Fray". Using both extensions together you can selectively request full buffer of video files.
