Firefox tabs.executeScript para la extensión de velocidad de reproducción no funciona

Tengo un configurador de velocidad de reproducción simple para cualquier video etiquetado con HTML (YouTube).

Cuando hago clic en el botón 2.25 que se supone que cambia la velocidad, no pasa nada.

Pero cuando abro la consola del navegador y escribo "document.querySelector('video').playbackRate = 2.25", el video cambia bien su velocidad.

¿Cuál es la solución?

velocidad de juego.js

 browser.tabs.executeScript( { code: `document.getElementById('speed225').onclick = function () { document.querySelector('video').playbackRate = 2.25; }` })

botones-de-velocidad.html

 <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <link rel="stylesheet" href="style.css" /> </head> <body> <div id="popup-content"> <div class="button" id="speed225">2.25</div> </div> <script src='playspeed.js'></script> </body> </html>

estilo.css

 html, body { width: 100px; } .button { margin: 3% auto; padding: 4px; text-align: center; font-size: 1em; cursor: pointer; background-color: lightgray; } .button:hover { background-color: rgb(196, 230, 196); }

manifiesto.json

 { "manifest_version": 2, "name": "Video Playback Speed Controller (Menu Bar)", "version": "1.0", "description": "Adds buttons in the menu bar to change playback speed for HTML video tagged videos.", "icons": { "48": "icons/playback-icon-48.png" }, "permissions": [ "activeTab" ], "browser_action": { "default_icon": "icons/playback-icon-32.png", "default_title": "Change Video Speed", "default_popup": "speed-buttons.html" } }
