Firefox

The Firefox 86 update went live last week. By far, the most important feature is the implementation of State Partitioning (or Total Cookie Protection).

"Our new feature, Total Cookie Protection, works by maintaining a separate “cookie jar” for each website you visit. Any time a website, or third-party content embedded in a website, deposits a cookie in your browser, that cookie is confined to the cookie jar assigned to that website, such that it is not allowed to be shared with any other website."

More details about this update, as well as the rest of the release notes are available in the following articles:

WebKit

Safari Technology Preview 121 is out now, adding support for aspect-ratio on grid items and a lot of other updates.
