Firefox is one of two major browsers left with a non-Chromium engine (the other being Apple’s Safari), which means it can experiment with lower-level changes that Google isn’t interested in. Now one of those changes is rolling out to everyone: Total Cookie Protection.
Mozilla has announced two new features for its Firefox browser on Mac, Windows and Linux. It is introducing multiple picture-in-picture (multi-PiP) and a way to combat cross-site cookie tracking once and for all. The later is being called Total Cookie Protection (technically known as State Partitioning or Dynamic First-Party Isolation).
Up until now, you were allowed to view one window in picture-in-picture (PiP) mode. Now, Mozilla is expanding Firefox’s capabilities. Have you ever wanted to view multiple videos at once in PiP? You will now be able to. The company is adding multiple picture-in-picture views. It will be available on Mac, Linux and Windows. It also includes keyboard controls for fast forward and rewind.
