Nope. Not working for me. Results still show shorts.

I have already tested it in my environment and it still works perfectly.
Have you disabled the "Hide Shorts Video" feature?
Or could you provide your environment parameters or YouTube account?"

Environment parameters? U mean what browser on what platform?

Environment parameters? U mean what browser on what platform?
That'd be Firefox 111.01 32-bit on Win 10.
And it's enabled.

Bro, the homepage of this script has already written a Notice.
And your Firefox version is less than 120, you need to go to enable layout.css.has-selector.enabled.
Take a look at https://caniuse.com/css-has.

Snapshot. Too bad the limit is at 241kb... which is ridiculous to view clearly. Oh well..

Tried after updating. Nope. Still don't work.

See? Even after setting to True.

I believe Google is up to no good again. They're kinda active attempting their best ruining anti ads scripts and extensions. My youtube has been acting weird just few hours back. It plays the audio multiple times of the same video i click on. The audio gets louder as each plays at few gap of seconds. The only way for me to remove shorts from being shown in my result is to deactivate ublock-origin, then click on the filters menu in youtube, switch to pref of highest duration of videos upon my search and then... of course i won't have shorts videos that way.

I found the problem.
Please change your script manager to Tampermonkey or Violentmonkey.
As the Greasemonkey v4.0+ has already discontinued support for the "GM_" APIs.

Owhh.. that now. Ok, will try yet again.

Ok, seeeem to work with Tampermonkey. But i can't be sure if all it did was just remove the shorts badge of some of the video results i got or really got it off completely. It does have embedded keywords in hash of "shorts" in those videos. So that's where i doubt what the script really did.
