Let's make the web work for everyone

In today’s mobile-first world, testing every user touch-point, especially on mobile devices matters more than ever. The web should work for everyone, no matter where, how and on what devices they access their favorite content.

Mozilla and BrowserStack are partnering so we can reach more developers than ever and provide them with the tools to help them ship great experiences to every user, every time.
