Mozilla released Firefox 86.0 Stable and Firefox 78.8 ESR to the public on February 23, 2021. The new versions of the browser are already available as direct downloads from the Mozilla website and as in-browser updates.
All development versions of Firefox are updated as well around the same time. Firefox Beta and Firefox Developer are moved to version 87, Firefox Nightly to version 88, and Firefox Android to 86.0 as it follows the stable channel's versioning.
You can check out the Firefox 85.0 release overview in case you want to take a look at it.
Firefox 86.0 is available by the time this article is published. Firefox users may select Menu > Help > About Firefox to check the installed version and run a manual check for updates. Unless deactivated, updates will be pushed automatically to Firefox installations.
Manual downloads are also available. The following pages list direct downloads for supported Firefox channels.
Multiple picture-in-picture windows
Firefox users may open multiple picture-in-picture windows in the new release instead of just one. Each stream needs to be opened in its own tab in the browser, and the actual picture-in-picture windows may be moved around to view them all at once.
While it is not a mass-market appeal feature, it is useful for certain scenarios, such as following multiple matches on match day, or watching an event unfold through different camera perspectives.

Total Cookie Protection
Total Cookie Protection is a new privacy feature designed to separate cookie data by website. Each site gets its own cookie storage and that means that access is restricted and not shared across all Internet sites.
Mozilla notes that it decided to make exceptions for non-tracking cookies that are cross-site that are needed, e.g. for sign-in purposes on sites. The organization notes:
Only when Total Cookie Protection detects that you intend to use a provider, will it give that provider permission to use a cross-site cookie specifically for the site you’re currently visiting
The new feature is enabled automatically when you enable the strict mode of Firefox's Enhanced Tracking Protection feature. Firefox users who want to try the new option may point their browser to about:preferences#privacy to set the Enhanced Tracking Protection preference to Strict on the page.
Firefox for Android
Security updates are revealed after the official release of the web browser. You find the information published here after release.
Firefox 87.0 will be released on March 23, 2021 according to the Firefox release schedule.
