// 1. Ensure you are signed in (if not, visit https://vimeo.com/log_in).

// 2. Set `VIMEO_CHANNEL_ID` below to the channel ID corresponding to the channel you want to add the video to.
//    The channel ID appears at the end of the channel URL (e.g., https://vimeo.com/channels/1434599).
//    See the other script for a snippet to run to navigate to your list of channels.

// 3. If you're logged in, from a video page on Vimeo, enter this in the Console from your browser's Dev Tools:

VIMEO_CHANNEL_ID = 1434599; document.querySelector('.collections-button').click(); setTimeout(() => { document.querySelector(`input[id="${VIMEO_CHANNEL_ID}"]`).checked = true; }, 500); window.close();

Using Myk Melez's qbrt project, @cvan's maintained a forked branch, vr, as the foundation for building a standalone, self-contained executable of Desktop Firefox w/ enabled-by-default WebVR Support.

Done in March – April 2017 at Mozilla in the Mixed Reality program, this experiment was led by @cvan and @caseyyee, codenamed Moonrise.

• Moonrise could generate Windows, macOS, and Linux releases of a wrapper program of this branch of qbrt.
• Moonrise's default start page was a WebVR-powered Lobby experience
• Moonrise could connect to a user's Steam account (if the user was already locally authenticated in the Steam app, Steam's user-management APIs worked witho

Forcing a better default playback quality of YouTube videos

If a user is browsing videos on YouTube.com from a web browser on a higher-end device (e.g., VR headsets), the user has to manually override the playback quality of a video through the playback-controls bar at the bottom of the video: Settings > Quality.

---

Forcing a different playback quality of a YouTube video

1. Load a YouTube video. Example: https://www.youtube.com/watch?v=ELU-43DMNT4
2. Then paste some of this code in the DevTools' Console.
3. You'll notice the quality changes to the highest available for the video.
