A little orange duck has appeared in the bottom right of my screen. He asks, "Can I help" does voice recognition, I think. But it is annoying, and will not go away. How do I discourage this little creature from bothering me?

    @PerlDuck Nothing is wrong with cute little rubber duckies. They are especially good for bouncing ideas off of. However, when they start talking back it can be unnerving.

    Quack Overflow would be a great name for an "online doctor" site. However, this duck is annoying. I don't want my computer making noises while I'm at work; but as far as I can see, you can't kill this annoyance without it making a noise. Whose idea was it that "my joke is so important, it must be as difficult to kill as possible"? Commented Mar 31, 2018 at 21:21

    @yo' Actually I was just kidding because I share (part of) the duck's name. Indeed: now it starts to annoy me as well because April 1st is a while ago now. Dunno what timezone that QuackOverflow thingy is in, but it's definitely NOT somewhere on earth.

How to send the duck away

While I don't know why you would like to remove the helpful ducky, here are the necessary steps.

Tell the duck 'goodbye'

You have to both "hate this duck" and say goodbye as can be seen in the source code:


Only the last "goodbye" button will set the quack cookie and therefore disable the duck. Keep in mind that you have to accept cookies from cdn.sstatic.net, otherwise the change won't be permanent.

Scare it off programmatically

Alternatively, run the following code in your console:

$(".quackoverflow").hide() && $.cookie("quack",1,{"path":"/","expires":3})

You can also use this in a bookmarklet:


But the duck haunts me on other sites!

Note that the cookie is site specific. You need to say goodbye on every site you visit. Alternatively, block the https://cdn.sstatic.net/Js/quack.en.js script, which removes the duck entirely from your reality.

    Yes, but if you do, and change sites, for example to cross validated, our little friend reappears.

    @Carl right, because it's a site specific cookie.

  • @Ooker it's just url we need to block (cdn.sstatic.net/Js/quack.en.js), where potential mutable parts replaced with *. I watched syntax here and checked things work, don't know if there's more correct way. Commented Apr 1, 2018 at 13:04

There is an option to remove this duck after it quacks once. Click on "I hate this duck". It understands and disappears.

Solved. Look at April fools info for the tag. It lists "quack exchange" as this year's joke. Other users suggest that adblocker will work on it. For my part, I will ignore the little fellow. We have been suckered.


In order to hide it, you have to click "I hate this duck" and "Goodbye" (after it "listens") to make it disappear. However, as mentioned in another answer, you can get rid of it off programmatically using $(".quackoverflow").hide(). But it's still site-specific, meaning it has to be manually dismissed on every site.

So I created a userscript (Tampermonkey) to hide it automatically.

Alternatively, using an ad blocker (or something else to block the script) also works.

Also, Quack Overflow is the April fools joke this year.

For uBlock Origin on Chrome:

  1. Click the extension badge in the upper right.
  2. Click the sliders icon to "open the dashboard."
  3. Switch to the "my filters" tab.
  4. Put ##.quackoverflow in the text box.
  5. Click the "apply changes" button above the text box.

This affects all sites (including any non-SE sites that name classes quackoverflow for some reason, if they exist).


With AdBlock adding stackexchange.com##DIV[class="quackoverflow z-modal ps-fixed r24 js-quackoverflow is-visible"] killed it on every site in the network except SO, where it needs a separate line owing to a different domain.

By the way, the Clippy flashback was very much not appreciated, even as April 1st feature.
