All StumbleUpon accounts will be moved over to Mix.com. Some 40 million users, including myself, may have fond memories of stumbling through the internet by incessantly clicking the "Stumble" button — which you could add as an extension on the Firefox web browser.

Why did they get rid of StumbleUpon?

Why did StumbleUpon shut down? StumbleUpon has been running since 2002, but didn't adapt its interface quite enough to compete with today's top social media platforms. So it just didn't have the same popularity-driven growth that could sustain it, unlike websites such as Facebook, Twitter, or Instagram.

Does StumbleUpon still exist?

Sixteen years after it started, StumbleUpon called it quits. It ceased operations forever on June 30, 2018. But don't worry, there are still some StumbleUpon alternatives that let you find interesting web pages with the click of a button.
