Quote:Mozilla has released the latest version of Firefox, Firefox 95, for Windows and macOS. It's available now for all users on both platforms.

The Firefox team says the new macOS version reduces CPU usage during event processing and that power usage is reduced while streaming video from sites like Netflix, "especially in fullscreen." macOS users will also get a faster content process startup and will enjoy memory allocator improvements for better overall performance.

On both macOS and Windows, Mozilla has "improved page load performance by speculatively compiling JavaScript ahead of time." There's also a way to move the picture-in-picture toggle button to the opposite side of the video on both platforms, plus a handful of fixes.

But those optimizations and tweaks aside, Firefox 95's best enhancements have to do with security, as RLBox is now enabled on all platforms. Mozilla published a detailed blog post explaining what RLBox is and how it works, but the quick summary is that it's a new sandboxing technique that isolates potentially problematic code in WebAssembly and protects users from threats.
