Short answer: This mute list does not work, and has never worked. TylerBussell confirmed as much three years ago.

Thank you for explaining that the word contents within the script do nothing. However, I'm simply trying to get the script itself to work to auto-add muted words other than the contents within the script, such as #ad, and adult/crypto related terms. Unless (like you said) I am going through some kind of placebo effect, or misremembering something, this script was applying new words to my muted list, and that is all I am looking for assistance with at this time.

Hey, I know it's sound like an ad, but I had the exact same issue and wanted to add lists of muted words because for some reasons Twitter only allow to add them one by one...
I created a small browser extension where you can enter a URL from github gist or pastebin and automatically add dozens of muted words. Check it if you want to (beta)test, I'm the only user right now and need some feedback ^^ https://www.chirpsilencer.com/

I can confirm this works on chrome! I I do recall getting caught up with a maximum number of words I could mute which is unfortunate. For now I finished adding my list manually, but I just thought I'd mention this to you and hope it looks for duplicates. Hope it works for Firefox eventually

Glad to hear it.

As far as the limit is concerned, it does exist within Twitter, which is a bit impractical...

As soon as I have a bit of time I'll start converting the Firefox extension. For the moment, simply transferring from one to the other doesn't work and will require a few adjustments.

Mozilla just approved the plugin https://addons.mozilla.org/fr/firefox/addon/chirp-silencer/

Need some tests because I had to change some key elements in it...

This bookmarklet prompts for a comma-delimited list of terms (including phrases), scrapes existing terms to avoid duplicate errors, and offers the full updated list in an "I'm done" message. Play with the delay.

javascript:(function(){const delayMs=500;let input=prompt("Enter comma-separated muted keywords:");if(!input)return;const keywords=input.split(",").map(s=>s.trim()).filter(Boolean);const nativeInputValueSetter=Object.getOwnPropertyDescriptor(window.HTMLInputElement.prototype,"value").set;function getMutedKeywords(){let arr=[];document.querySelectorAll("section[aria-label='Section details'] div[role='link']").forEach(el=>{let span=el.querySelector("div[dir='ltr'] span");span&&arr.push(span.textContent.trim().toLowerCase());});return arr;}function addMutedKeyword(kw){const inp=document.querySelector("[name='keyword']");nativeInputValueSetter.call(inp,kw);inp.dispatchEvent(new Event("input",{bubbles:true}));document.querySelector("[data-testid='settingsDetailSave']").click();}const delay=()=>new Promise(r=>setTimeout(r,delayMs));keywords.reduce(async(prev,kw)=>{await prev;let existing=getMutedKeywords();if(existing.includes(kw.toLowerCase())){console.log("Skipping duplicate:",kw);return Promise.resolve();}let addButton=document.querySelector("a[href='/settings/add_muted_keyword']");if(!addButton){console.error("Add muted keyword button not found, skipping keyword:",kw);return Promise.resolve();}addButton.click();await delay();addMutedKeyword(kw);return delay();},Promise.resolve()).then(()=>alert("I'm finished.")).catch(e=>{console.error(e);alert("Finished with errors: "+e.message);});})();
