Mozilla Brings Containers to Firefox 153, Isolating Cookies Across Work and Personal Tabs

Summary
Firefox 153 now includes a preview of native Containers, letting users keep work, shopping, personal and banking sessions logged in separately within one browser window.
Built into Firefox rather than offered only as an add-on, the feature isolates cookies and ad tracking by container so activity in one context is not visible to another.
The preview lets users open tabs in specific containers and customize names, colors and icons, while managing setup directly in Firefox settings or from the tab menu.
Mozilla said the move brings nearly a decade of Multi-Account Containers functionality into the browser core, though some extension features are still missing and the add-on can still run alongside it.
Firefox 153 is Mozilla's latest stable release and the first step in a broader push to make context separation a built-in part of future browsing features.
