Firefox Test Pilot is flying off into the sunset on January 22nd, 2019. Currently active experiments will remain installed for all users, and will be available on addons.mozilla.org after this date. Non-extension experiments like Firefox Lockwise and Firefox Send will continue in active development as standalone products.
First thing’s first: if you are using any currently active add-on experiment, you can keep using it. Nothing’s going to change in your browser, we’ll just automatically migrate you off of the Test Pilot versions of the add-ons.
Firefox Send and Firefox Lockwise will continue in active development in 2019 as standalone products. Notes, Firefox Color, Side View, Price Wise, and Email Tabs will all remain available at addons.mozilla.org for the foreseeable future. Email Tabs in particular may undergo some changes to make it more flexible and less directly connected to Gmail; otherwise, these projects will be accessible in their current forms with occasional maintenance releases going forward.
As for the Test Pilot site and add-on, we are replacing the site with a farewell message on January 22nd. Visiting the site after this date will automatically uninstall the Test Pilot add-on, but you can also just uninstall it manually if you wish whenever you like without affecting installed experiments.
Leave Test Pilot
You can leave all experiments and uninstall Test Pilot before January 22nd if you'd like. Click the … icon at the top right corner of the Test Pilot home page or any experiment page and then click
You’ll see a message asking you to confirm. Click “Proceed” to leave Test Pilot. This will disable all of your active experiments.
