Starting from December 14, Firefox extensions that are marked as compatible with Android will be available to all Android users. Mozilla announced this in a blog post.
In the official browser extension store, the company has also created a separate page for those that will be available on Android.
“We’ve been so impressed with developer enthusiasm and preparation,” said Giorgio Natili, Firefox Director of Engineering. “Just a few weeks ago it looked like we might have a couple hundred Android extensions for launch, but now we can safely say AMO will have 400+ new Firefox for Android extensions available on December 14. We couldn’t be more thankful to our developer community for embracing this exciting moment,” said Giorgio Natili, director of development at Firefox.
Mozilla also encourages developers to update their extensions and add Android compatibility to them. To do this, they suggest watching webinars by Senior Developer Relations Engineer Simeon Vincent, one of which tells about the basics of extension migration, and the second one is about configuration and testing.
