Script to remove all videos from Youtube Watch Later playlist

Remove videos from Youtube Watch Later playlist.md

UPDATED 22.11.2022

It's been two years since the last update, so here's the updated working script as per the comments below.

Thanks to BryanHaley for this.

setInterval(function () {
    video = document.getElementsByTagName('ytd-playlist-video-renderer')[0];

    video.querySelector('#primary button[aria-label="Action menu"]').click();

    var things = document.evaluate(
        '//span[contains(text(),"Remove from")]',
        document,
        null,
        XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,
        null
    );

    for (var i = 0; i < things.snapshotLength; i++) 
    {
        things.snapshotItem(i).click();
    }
}, 500);

Non-english users will need to change "Action menu" and "Remove from" to what YouTube uses for their localization.

To remove hidden videos. Click the dots in Watch Later playlist and select "Show unavailable videos" then run this version of the script:

setInterval(function () {
    video = document.getElementsByTagName('ytd-playlist-video-renderer')[0];

    video.querySelector('#primary button').click();

    var things = document.evaluate(
        '//span[contains(text(),"Remove from")]',
        document,
        null,
        XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,
        null
    );

    for (var i = 0; i < things.snapshotLength; i++) 
    {
        things.snapshotItem(i).click();
    }
}, 1000);

This one also works really well. It might be slow, but is running in the background now.
