Script works on console but not on Chrome Tampermonkey

I ran inner essence of the function of the following script in non strict mode in console just fine but it doesn't run in Chrome Tampermonkey after I saved it (when it's enabled) and fully restarted the browser. Tampermonkey itself is also enabled of course... Maybe I'm missing something here by means of strict Js (which I've yet to learn)?

(function fbPurity () {
    'use strict';

    var chat = document.querySelector(".noGrip");
    chat.style.display = "none";

})();

Hello Ben Aharoni

I'm not familiar with Tampermonkey. Looks like it's a tool for creating userscript (greasemonkey) scripts. We don't teach that tool, so I'm afraid I won't be able to assist you with any problems specific to Tampermonkey.

The 'use strict'; statement should have no effect on this. Are there any specific errors you are seeing? Your code looks like it's specific to a particular page (or DOM) since it references a particular class name.

Hi dear Dave! While there were no errors the problem was, as clued from your answer, that I didn't configure the matched page right... The script was setted to work with the default tampermonkey test page. My mistake was when I first created the script (that hides an annoying feature in Facebook pages), I thought that if I create it in facebook.com it will then automatically be applied to all pages in Facebook, but of course I was wrong and now when the match is:

// @match      https://www.facebook.com/*

It does work on all FB's pages.

So, thank you for giving me this direction!

Ben,
