Mozilla has released another version of its web browser, introducing several practical new features. The most important is the built-in Containers feature, which makes it easier to separate personal activity from work activity. The feature was previously available only as the Multi-Account Containers extension, but it has now been integrated directly into Firefox. This lets users manage multiple accounts more conveniently without having to switch profiles or use private browsing mode. The update also includes improvements to video playback, PDF editing, and security. Firefox 153 is already being rolled out gradually to users on the browser's stable channel.

Built-in Containers help separate different online activities

The new Containers feature lets you open tabs in isolated spaces that don’t share cookies, login data, or site data. This allows you to use multiple accounts on the same service at the same time without them affecting each other. For example, a work Google account can remain completely separate from a personal YouTube account, and banking sites can be kept apart from online stores. Firefox offers default categories such as Personal, Work, Banking, and Shopping, but users can also create their own Containers. Each one gets its own name, color, and icon, which makes them easy to recognize. To open a new tab in a chosen Container, just right-click the tab and select the appropriate option. The basic functionality is now integrated into the browser, so it no longer requires installing an additional extension.

Firefox 153 also brings HDR, improved PDF editing and new security features

Aside from Containers, Mozilla has also introduced a number of other improvements. Firefox 153 allows HDR playback on Windows PCs with a compatible display and HDR enabled. The browser also lets you share web pages via QR codes. The PDF editor has been enhanced and can now merge documents and add images as new pages. A color picker available from the address bar has been added, as well as experimental support for the JPEG XL format through Firefox Labs. Mozilla has also increased security: extensions must now request separate permission to access local files, and websites require user consent before connecting to devices on the local network.

Firefox 153 is an update focused on user convenience and security. Built-in Containers make it easier to separate work from personal life, and features such as HDR, an improved PDF editor, and new privacy protections make the browser even more capable.
