Firefox Beta is available for download for Windows, Linux and OS X. The new version offers the following features:
- On macOS, the WebGL performance settings allow non-performance-critical applications and applets to request the low-power graphics processor instead of the high-power graphics processor in multi-GPU systems.
- Improved Windows 10 integration: Your Firefox theme now fits your OS Dark / Light mode.
- WebExtensions now run in a separate process under Linux.
- Faster switching of tabs in most cases for our macOS users.
- Improved Firefox responsiveness on macOS.
