Firefox finally unveils its faster, more memory-efficient browser
The team behind open-source browser Firefox has released a much-awaited version that promises to be faster and less of a memory hog. Version 54 is the first to use "multiple process" tech that has been available for a while now on Chrome, Safari, Edge and other browsers. Now, Firefox tabs running heavy, complex websites will impact other tabs less, making the web run better overall on Windows, Mac and mobile devices.
