How to Enable Firefox Proton Now

In May of 2021, Firefox will be getting a long-overdue new look and interface code-named Firefox Proton. Here's how you can check out Firefox Proton now.



You will need to download and install the latest beta or Release Candidate. Keep in mind that Mozilla will update the beta until Proton is made widely available in May. What you see today should change as we move forward.
