How can I contribute?
First, you will want to take a look at our CONTRIBUTING.md file.
If you'd like to contribute to an experiment, take a look at the experiment's detail page on Test Pilot for the most up to date link to the experiment's repository.
I used to see an experiment, but now it's missing?
We've recently shipped localization for Test Pilot and decided to restrict experiments from certain locales to ensure a smooth roll out. We didn't uninstall any experiments, but if your default language is German, some experiments may have been hidden from Test Pilot.
Experiments you've previously installed are still accessible through
about:addons and can be uninstalled from there. It's also possible that the experiment you're looking for has already graduated.
You can see graduated experiments by clicking on the
View Past Experiments button on Test Pilot.
Where can I file a bug?
Test Pilot bugs can be filed on the Test Pilot GitHub repo. link
You will find a link to report bugs for individual experiments on the experiment's detail page on Test Pilot for the most up to date link.
