I'd like to disable Wikipedia's article previews that are shown when hovering over a link:

I know I can disable those when being logged in but most of the time I'm using Wikipedia without being logged in. I also delete my cookies regularly.

I hoped that there would be a Greasemonkey script to disable them but I couldn't find anything relevant on OpenUserJS or Greasy Fork.

I'm using Firefox.

There is no need for a script. Wikipedia gives you the option via a pop-up no matter the browser.
Even not logged in you can turn it off by:

  • Hover over any article link.
  • On the preview, click on the gear icon in the bottom-right corner.

  • Select "Disable" in the pop-up and then "Save".

  • Thanks for your answer! This works until I restart Firefox (I delete all the cookies when exiting). Commented Dec 2, 2019 at 18:17
  • "This works until I restart Firefox (I delete all the cookies when exiting)". That is the whole idea of cookies.

    I appreciate your answer. I was hoping for a solution that doesn't rely on cookies since, as I stated in the question, I clear them regularly for privacy reasons and as far as I know there's no option in Firefox that would exempt cookies of certain sites from deletion.

  • "I appreciate your answer. I was hoping for a solution that ..." This is as good as it gets. ¯_(ツ)_/¯ Commented Dec 3, 2019 at 16:41
  • @MatthiasBraun I agree, if a user is interested in their privacy then this answer is not a solution. Wiki is enabling this for all users and is another example of unchecked propaganda techniques forcibly bullying users into making them view unwanted stimulus. I know the legal system will be helpless in these situations. But developing much safer browsers are possible - including machine learning (AI) powered ad blocking technology to end this era of nonsense for good.

I wrote a Firefox add-on to disable these previews:

screenshot with add-on

All the add-on does is this, which disables the previews:

localStorage["mwe-popups-enabled"] = 0;

Its source code is here.

The add-on works for users that aren't logged in to Wikipedia and regularly delete their browser state (e.g., localStorage, cookies).
