Wikipedia has added page previews to the desktop version of the site. These page previews mean you can see what’s lurking behind a link before actually navigating away from the page you’re reading. Which, for a site as vast as Wikipedia, could be invaluable.
Wikipedia Adds Page Previews
Wikipedia has millions of entries for anything and everything you can think of. And all of these entries contain links to other Wikipedia pages. Which makes it very easy to lose a whole afternoon just clicking through from one page to the next.
Wikipedia’s solution to this problem, which some people refer to as the Wikipedia rabbit hole, is page previews. These are exactly what you would expect them to be; previews of the pages lurking behind links, which pop up when you hover your cursor over one.
Wikipedia’s page previews contain the first few sentences of the article behind the link, along with an image (if one is available). This saves you from having to click through to that article only to find it isn’t actually that interesting.
If you find page previews more annoying than useful rest assured it’s possible to disable them. Just open a page preview, click the settings cog, hit Disable, and Save. To enable page previews again just click the link at the bottom of any page, hit Enable, and Save.
