Mozilla is rolling out a new profiles feature in its Firefox browser starting October 14th, designed to make it easier for users to organize and separate their online activities.
The update lets users create dedicated browsing spaces—each with its own bookmarks, logins, history, extensions, and themes. This allows people to build distinct environments for work, personal use, or specific projects.
While Firefox already offers the Multi-Account Containers extension for managing cookies and tracking data, the new profiles feature expands that concept by offering full browser-level separation.
Each Firefox profile can be customized with unique avatars, colors, and themes, making it easy to distinguish between different profiles at a glance. The setup works similarly to Google Chrome’s profile system but with enhanced privacy controls and no need to create multiple accounts or email addresses.
“Profiles in Firefox aren’t just a way to clean up your tabs. They’re a way to set boundaries, protect your information, and make the internet a little calmer,” Mozilla said in its announcement.
Mozilla believes the new feature will help users reduce distraction and prevent mishaps—like accidentally sharing personal content in a professional setting—by keeping every browsing context neatly isolated.
