Mozilla wants to know if Containers help organize tasks and protect your online identity by keeping some aspects of your online use separate from others. Participating in this study will help us find out!

What will happen next

If you agree to participate:

  1. We will add additional functionality to Firefox that provides Containers for your tabs.
  2. You will see a new browser icon and panel to manage your Containers and Container tabs.
  3. You will see a new menu when you long-press on the "+" button in tab bar.
  4. Continue using Firefox - with or without Container tabs.
  5. After 28 days, the study will end on its own. Your Firefox will go back to normal. Any Containers you created and used during the study will be removed.
  6. We will ask you to fill out a quick optional survey to tell us about your experience. The survey should take less than 5 minutes to complete.

Leaving the study

The study will expire on its own in 28 days. You may leave the study early. To do so, follow these steps:

  1. Type about:addons into the location bar, and press enter.
  2. Find Containers Experiment in the extensions list pane.
  3. Click the remove button.
  4. If you opt out of the study early we will ask you to fill out a survey. We’re interested in hearing about your experience, even if you didn’t participate in the entire study.

Opting out of a study does not prevent you from participating in future studies.
