Firefox 94 adds plenty of new features, closes over a dozen security holes
Mozilla's release notes detail the updates, which include performance, security, and privacy enhancements.
Firefox will no longer prompt Windows users for updates, instead downloading and installing updates even when Firefox is closed. In Windows 11, Firefox will now support Snap Layouts menus.
On MacOS, Firefox will now use Apple's low-power mode when viewing videos in full screen on some streaming sites, which Mozilla says should significantly increase battery life on MacBooks. Firefox 94 is also supposed to decrease power consumption in Linux by enabling the EGL backend, which should increase WGL performance. What's more, Mozilla's browser will now automatically unload inactive tabs, but users can also view the memory consumption of each tab through an "about:unloads" page from which they can manually unload them without completely closing them.
