A new browser is being developed by Mozilla Research. It's called Servo and it's getting ready to become a reality, according to a post on the Forum by a developer from the development team. The post confirms that the first beta release should happen in June.
Servo is a browser engine built from scratch in Rust and aims for better performance, more security, and better parallelism.
What does parallelism mean in a browser? Independent browser components, such as rendering, HTML parsing, layout, and other tasks, are handled by individual processes, which helps with both performance and stability.
The team hopes to have a working alpha version in June so early adopters can start testing and providing feedback.
For many, the Servo project is a more interesting project than Mozilla Firefox because it is a completely new attempt to create a completely different browser.
We don't know if bits from Servo will eventually make it to Firefox, as it's not yet clear whether the company intends to merge the two projects.
