RegretsReporter Privacy Notice



When Mozilla receives information from you, our Mozilla Privacy Policy describes how we handle that information. Below are the top things you should know about RegretsReporter. You can also view the code here, which includes detailed technical information on what data is collected.

General Data Collection Principles

  • You must be 18 or older to use RegretsReporter.
  • No data is collected from inside Private Browsing windows.
  • The collected data is linked by randomly generated data ID:s used for this particular extension only. They are used to keep a specific user's data together on the server, helps us improve our analysis and allows us to fulfill data deletion requests. These ID:s are deleted when the extension is uninstalled, after which it is no longer possible to tie the collected data back to the browser from which it was collected.
  • Only a small number of Mozilla researchers will have access to raw data (temporary change during the staff test, see note at the bottom of this page).

Information We Collect

By default, Mozilla receives the following information:

  • YouTube usage statistics updates: Mozilla receives this update on every extension load and roughly every 24 hours. The following statistics are supplied, both as total sums and bucketed by their recommender system origin where relevant (non-search algorithmic recommendations content, search results, or recommendations with an explicit query or constraint to optimize for):
    • Amount of days of at least one YouTube visit
    • Amount of time with an active YouTube tab
    • Amount of YouTube video (watch) pages loaded
    • Amount of days of at least one YouTube video (watch) page loaded
    • Amount of time with an active YouTube video (watch) page tab
    • Amount of days of at least one video played on a YouTube watch page
    • Amount of videos played on YouTube watch pages
    • Amount of YouTube video play time
    • Amount of YouTube video play time on YouTube watch pages
  • Technical data: Mozilla receives basic information from the extension and the devices it's installed on, including information such as operating system, browser, language preference, country, and timestamps. When RegretsReporter sends data to us, your IP address is temporarily collected as part of our server logs and is deleted within 90 days.
  • Information about add-on errors: Mozilla receives information about reasons for errors, UI interactions preceding errors, and stacktraces. The host and pathname of some YouTube URLs may be included. To opt-out of automated error reporting in Firefox: right-click the RegretsReporter toolbar icon, choose “Manage Extension”, select the Preferences pane and uncheck “Allow RegretsReporter to send information about encountered errors to Mozilla." In Chrome: right-click the RegretsReporter toolbar icon, choose “Options” and uncheck “Allow RegretsReporter to send information about encountered errors to Mozilla."

If you specifically choose to submit a Regret report, Mozilla will also receive the following information:

  • Video metadata (The video ID, title, description, posting date, view count at navigation)
  • URL Type (What kind of YouTube page that was visited (e.g. Video Page, Homepage, or Search results)
  • Video element play time (in seconds)
  • Document visible time (in seconds)
  • Page entry point (Up next, Homepage, Search results page, User page, Channel page, Direct navigation, Other, etc)
  • Via search results (True/False)
  • Via non-search algorithmic recommendations content (True/False)
  • Via recommendations with an explicit query or constraint to optimize for (True/False)
  • How the video was reached / "How you arrived at this video" (Metadata for up to the past 5 YouTube pages visited in the last 5 hours leading up to the initiation of the report. This includes URL Type and, for video pages, video metadata, page entry points, document visible time and video element play time.)
  • Report identifier (A randomly generated identifier that is unique for each video reported)
  • From which step in the regret report form the report was sent from
  • User-selected regret categories (false, offensive, bizarre, other)
  • User-selected other regret category (if applicable)
  • User-selected severity rating
  • User-specified optional comment

Information We Disclose

Insights from the RegretsReporter extension will be used in Mozilla Foundation's advocacy and campaigning work. These insights will be shared with journalists working to investigate these problems and technologists working to build more trustworthy AI. When we disclose information, we disclose it in a way that minimizes the risk of you being re-identified.

Mozilla RegretsReporter shares information with a third party to provide the service to you. Mozilla has contracted with this company requiring them to protect your information. Here’s who we use to support RegretsReporters:

  • Google Cloud Platform: We use Google Cloud Platform (GCP) as our cloud computing service. GCP receives your computer’s IP address, the YouTube usage statistics, and Regret Reports.

Data Privacy Questions?

While the extension is installed, it is possible to send a data deletion request. In Firefox: right-click the RegretsReporter toolbar icon, choose “Manage Extension”, select the Preferences pane and click “Send Data Deletion Request." In Chrome: right-click the RegretsReporter toolbar icon, choose “Options” and click “Send Data Deletion Request." This will send an automated message to us that triggers the deletion of previously collected data. To access the collected data, click the “Inspect Collected Data” button in the same preferences pane.
