Firefox 69 was launched yesterday and introduces new changes that will impact Flash-based content across the internet, including Pogo. As part of Mozilla’s long-term plans to phase out support for Flash by 2020, you will need to give Firefox permission to enable Flash on a site whenever the browser is started. You will likely need to do this with each browser session.
You will still be able to enable and play Flash-based Pogo games in Firefox, just with this added step. We apologize for the inconvenience.
This change will only impact Flash games and not any newer HTML5-powered games. We’re working hard to port our library of older titles to HTML5, as well as bring in some brand-new games along the way.
