Brave has rolled out Containers with the Brave Browser 1.92 release, giving its Chromium-based browser something Firefox users have had for years now. And no, it is not some pre-installed extension doing the work; this functionality is built right into the browser for Linux, Windows, and macOS.In this implementation, each container keeps its own cookies and site data storage separate from the rest, even if you visit the same website across containers. By default, this feature ships with four categories: Personal, Work, Social, and School. Each one of them can be edited or deleted to suit your workflow.The default Container categories are useful, I must say.You can make new ones too! I made one to test how containers worked, named it "It's FOSS," and picked a color and icon for it from the available options.The idea itself isn't new. Brave points back to a Mozilla concept doc from 2015 that laid out the original pitch for container tabs in Firefox, complete with cookie isolation, per-container icons, and even auto-naming.
