Mozilla has released Firefox 95, featuring a new version of its security sandboxing subsystem called RLBox, and additional performance and efficiency improvements for the macOS version of the web browser.
According to the release notes, RLBox is a new technology that hardens Firefox against potential security vulnerabilities in third-party libraries.
The sandbox subsystem works by compiling a process in WebAssembly before re-converting it into native code, which restricts its access to system memory and stops it from jumping to unexpected parts of the program, thus limiting its potential for exploiting vulnerabilities.
