The following pages list direct downloads for supported Firefox channels.
Picture-in-Picture Mode is available in Firefox for Windows
Windows users who run Firefox 71.0 may use the browser's picture-in-picture -- short PIP -- mode in the new version of the browser. PIP mode moves videos to their own window that acts independently (to a degree) from the tab and page they are embedded in.
All that it takes is to move the mouse cursor over the video area to display and activate the picture-in-picture option.
The video starts to play in its own area on the screen. Controls are a bit limited right now and some are only available on the webpage the video is embedded on.
The video remains visible if you switch tabs. It is not possible to close the browser tab however as doing so will close the video.
Mozilla plans to introduce picture-in-picture mode in Firefox for Mac OS X and Linux in the future.
New Certificates Viewer
Firefox 71.0 features a new certificates viewer. I reviewed the new version in August 2019 already and suggest you check out the article as it covers everything.
The redesigned certificates viewer opens in a tab in the browser and may remind users of the Firefox add-on Certainly Something which offers similar functionality.
Firefox for Android
None according to the release notes.
Security updates are revealed after the official release of the web browser. You find the information published here later today.
