Min Vid has graduated from Test Pilot. Keep an eye on WICG/picture-in-picture for a possible future in Firefox.

Build Status Available on Test Pilot

Min Vid is a Firefox web extension that gives you complete control over the videos in your browser. You can pop out, sticky, resize, and drag videos anywhere within the browser - it even stays visible when you switch tabs, so you can keep watching while you browse.

This is an experiment - seeing what happens when users have total control over the media they're consuming on the web. Users should be able to consume content in whatever way they feel comfortable. In the future we may be exploring these concepts with other forms of media, such as audio or pdfs.


Once the extension is installed you are able to launch Min Vid from the overlay icon over videos on YouTube and Vimeo.

You can also launch Min Vid by right clicking on a video link and sending to the player from the context menu.


  • npm install
  • npm run package (creates addon.xpi in the min-vid directory)
  • Open Firefox, go to about:config, set some prefs:
    • set xpinstall.signatures.required to false (allows unsigned extensions to be installed)
    • set extensions.legacy.enabled to true (allows legacy extensions, like min-vid)
  • install xpi by dragging onto the about:addons page

note The xpinstall.signatures.required option in about:config needs to be set in order to install unsigned extensions.


Contributions welcome. To get started,

  1. Clone the repo:

  2. Install packages: npm install

  3. npm run dev to watch for file changes while developing. (jpm watchpost has been disabled for this release, we are working on a way to add it back, in the meantime, you will need to manually dragndrop the xpi onto the about:addons page)
