Firefox for Mac and Linux to get a new security sandbox system

[silversurfer]

Mozilla will add a new security sandbox system to Firefox on Linux and Firefox on Mac.

The new technology, named RLBox, works by separating third-party libraries from an app's native code.
 
This process is called "sandboxing," and is a widely used technique that can prevent malicious code from escaping from within an app and executing at the OS level.
 
RLBox is an innovative project because it takes sandboxing to the next level. Instead of isolating the app from the underlying operating system, RLBox separates an app's internal components -- namely its third-party libraries -- from the app's core engine. This technique prevents bugs and exploits found inside a third-party library from impacting another project that uses the same library.

Work on RLBox began last year, in 2019. This new security sandbox model was developed as part of a joint effort between Mozilla and academics from the University of California San Diego, the University of Texas at Austin, and Stanford University.
 
RLBox will see its first deployment in Firefox 74 for Linux, set to be released next month, in early March. In April, RLBox will also ship for Firefox 75 for Mac.
