take a look at this post for a workaround

Time once again for me to share something helpful that can be used with one of my favorite extensions

{
    "createdBy": "Redirector v3.5.3",
    "createdAt": "2023-10-12T00:00:00.357Z",
    "redirects": [
       {
            "description": "YouTube>YewTube",
            "exampleUrl": "https://youtube.com/watch?v=ckatAzemRHk/",
            "exampleResult": "https://yewtu.be/watch?v=ckatAzemRHk/",
            "error": null,
            "includePattern": "^(?:https?):\\/\\/(?:\\w+\\.)?youtube\\.com(.+)?\\b",
            "excludePattern": "",
            "patternDesc": "Redirect Youtube",
            "redirectUrl": "https://yewtu.be$1",
            "patternType": "R",
            "processMatches": "noProcessing",
            "disabled": false,
            "grouped": false,
            "appliesTo": [
                "main_frame"
            ]
        },
    ]
}

I highly recommend grabbing the libredirect extension and having all youtube links redirect to freetube.

I’ve just been clicking the X to close that popup and nothing has happened to me.

I use the Invidious method; whenever I want to watch or share a YouTube video, I’ll copy and paste the section after the YouTube domain to the suffix of an Invidious domain.

For example, I take the “watch?v=fIvXc5D_Xjg” from https://youtube.com/watch?v=fIvXc5D_Xjg and paste it to the end of https://yt.artemislena.eu/.

This may also be a temporary work around, as YouTube can and will disrupt Invidious sites too if they accumulate enough traffic. The best long term solution is to encourage artists, journalists, and entertainers to share their free videos on PeerTube instances, and support federated video hosting.
