Mozilla has released a new version of its web browser, introducing several practical additions. The most important is built-in Containers, which make it easier to separate private and 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 switching profiles or using private browsing. The update also includes improvements to video playback, PDF document editing and security. Firefox 153 is already being rolled out to users of the stable release of the browser.

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 credentials or site data. That means you can 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 bank websites 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, colour and icon, which makes them easy to recognise. To open a new tab in a chosen Container, just right-click the tab and select the appropriate option. The core functionality is now built into the browser, so there’s no need to install an extra extension.

Firefox 153 także wprowadza HDR, lepsze pliki PDF i nowe zabezpieczenia

Obok funkcji Containers Mozilla wprowadziła też szereg innych ulepszeń. Firefox 153 umożliwia odtwarzanie materiałów HDR na komputerach z Windows wyposażonych w kompatybilny ekran i włączoną obsługę HDR. Przeglądarka pozwala także udostępniać strony internetowe za pomocą kodów QR. Edytor PDF został rozbudowany i potrafi teraz łączyć dokumenty oraz dodawać obrazy jako nowe strony. Pojawił się również próbnik colour dostępny z poziomu paska adresu oraz eksperymentalna obsługa formatu JPEG XL poprzez Firefox Labs. Mozilla zwiększyła też poziom bezpieczeństwa: rozszerzenia muszą teraz uzyskiwać osobne uprawnienia do dostępu do lokalnych plików, a strony internetowe wymagają zgody użytkownika przed połączeniem z urządzeniami działającymi w lokalnej sieci.

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