Researchers at the University of Texas at Austin (UT Austin), the University of California, San Diego, Stanford University, and Mozilla have developed a new Web browser security scheme.

Initially deployed in the Firefox browser for the Linux operating system, the WebAssembly mechanism was created to accelerate Web apps that run within a browser, while keeping those apps within "secure sandboxes" to prevent hijacking by malware.

The new RLBox framework relocates browser components that decode media files to these sandboxes.

UT Austin's Hovav Shacham said, "The hope is that at some point, bugs in all of those libraries become useless for hacking Firefox. And if that happens, then user security would be greatly improved."
