Mozilla rolls out improved Firefox profile management to keep browsing activities separate

Mozilla is rolling out a new profile management feature in Firefox, starting October 14, giving all users the ability to create multiple separate spaces. Each profile comes with its own bookmarks, logins, history, extensions, and themes, aiding users who need to separate work, school, or personal browsing. Previously, profile management was limited to Firefox’s about:profiles page and was less visible to most users, even though the functionality had existed since at least 2018.

With Firefox 138’s April 2025 launch, Mozilla introduced improved tools for managing profiles, but these changes were initially only available to a subset of users. The company noted that this gradual rollout was intentional, but by mid-October, the enhanced profile management will become available to everyone.

Alongside these updates, Mozilla collaborated with people with disabilities to design a more accessible interface, aiming to make profile management genuinely easy to use for all. These improvements help users set clear boundaries, protect personal information, and make online experiences less overwhelming.
