This gist is for mute/unmute tabs incase the official chrome extension goes down again

mute.js

async function toggleMuteState(tabId) {
    try {
        const tab = await chrome.tabs.get(tabId);
        const muted = !tab.mutedInfo.muted;
        await chrome.tabs.update(tabId, { muted });
    } catch (err) {
        console.error("Failed to toggle mute:", err);
    }
}

chrome.commands.onCommand.addListener(async (command) => {
    if (command === "toggle-mute") {
        try {
            const [tab] = await chrome.tabs.query({ active: true, currentWindow: true });
            if (tab) {
                await toggleMuteState(tab.id);
            }
        } catch (err) {
            console.error("Failed to query active tab:", err);
        }
    }
});

chrome.action.onClicked.addListener(async (tab) => {
    chrome.tabs.create({
        url: "help/index.html"
    })
});

chrome.runtime.onInstalled.addListener(({ reason }) => {
    if (reason === "install") {
        chrome.tabs.create({
            url: "https://browsernative.com/mute-tab-keyboard-shortcut-chrome-extension/"
        })
    }
});
