Revision Content

Shield studies let you try out different features and ideas before they are released to all Firefox users. Using your feedback, we can make more informed decisions based on what you actually need.

How do I participate?

When a study is available, you will be asked to participate. If you confirm your willingness to participate in a specific study, an add-on will be installed on your computer for the duration of the study.

When the study ends, the add-on will expire and you will be asked to fill out a survey.

How do I see the studies I'm in?

To see the studies you're participating in, type about:studies into your address bar.

How do I opt out?
