Firefox 86.0 is out today as the latest monthly update to this open-source web browser that continues to work on ramping up its security offerings.

Firefox 86.0 introduces "Total Cookie Protection" in strict mode where every website is then bound to its own "cookie jar" to better prevent sites from tracking users site-to-site. Firefox on Linux and Android also now mitigates against stack clash attacks. DTLS 1.0 support has also been dropped from WebRTC PeerConnections support.

Firefox 86.0 also enables support for simultaneously watching multiple videos in Picture-in-Picture mode, improved print functionality / UI design, and performance/stability improvements for canvas drawing and WebGL drawing to the GPU process.
