How it Works

When you send a YouTube Regret, the video and recommendations that led you to it are submitted to Mozilla researchers privately.

2 Report the video and recommendations that led you to it

3 Send any extra details you would like Mozilla to know

With the RegretsReporter extension, you can immediately take action to send us recommended videos that you regret watching—like pseudoscience or anti-LGBTQ+ content.

The report form will ask you to tell us more about your YouTube Regret and collect information about the recommendations that led you to the video. By sharing your experiences, you can help us answer questions like: what kinds of recommended videos do users regret watching? Are there usage patterns that lead to more regrettable content being recommended? What does a YouTube rabbit hole look like, and at what point does it become something you wish you never clicked on?

Let’s work together to make recommendation engines on the internet more trustworthy.

For years, journalists, researchers, and even former YouTube employees have been telling YouTube that they need to stop their recommendation engine from sending users down racist, conspiratorial, and other regrettable rabbit holes.

YouTube claims to be fixing this problem, but it’s all happening behind closed doors, without any way for the public to tell if it’s actually working. Last year, Mozilla gave YouTube three recommendations to help address this problem in a more open and transparent way. So far, YouTube has not made these changes.

That’s where you come in. Mozilla’s RegretsReporter browser extension transforms everyday YouTube users into YouTube watchdogs. We can use our own data to answer questions about regrettable recommendations that can go a long way towards helping journalists who investigate these problems, other groups like Mozilla who push for more accountability, and engineers and designers who build this technology.
