Version 48 of the Mozilla's web browser Firefox has just been released offering new features intended to improve the stability and security of the browsing experience. It is available for Windows, Mac, Linux and Android platforms.
The updated browser includes "multiprocess for Firefox for Desktop," in which the rendering engines work in a separate process from the browser shell, freeing up memory so screens won't freeze up.
Other browsers have long offered this. The developers at Firefox created a new extension system and created shim layers that enable developers to still support their old extensions.
Another security improvement is that Firefox 48 now requires extension signing. Any add-on that has not been verified and signed by Mozilla will not load.
The rollout of v48 is available to only around half of the user base at this point, with full rollout expected to increase gradually.
