A new program tourIt is developed by Mozilla Research. It's called Servo and it's about to become a reality, according to a developer post from the development team on the Forum. The publication confirms that the first release of a beta versions should be done in June.
The Servo is a Rust-built browser that aims at better performance, more security and better parallelism.
What does parallelism mean in a browser? The browser's independent components, such as rendering, HTML parsing, etc layout and other tasks are handled by individual processes, which helps both performance and stability.
The team hopes to have a working alpha version in June so that the first users be able to initiate testing and provide feedback.
For many, the Servo project is more interesting than Mozilla Firefox because it is a whole new attempt to create a completely different browser.
We do not know if finally Servos bits reach Firefox, as it is not yet clear whether the company intends to merge the two projects.
