Mozilla Firefox is about to add an important feature other browsers have had for years

If you use Google Chrome, Safari, or Microsoft Edge, you might take the profile management feature for granted by now. Chrome has had a profile manager for over a decade, but its open-source rival, Mozilla Firefox, is the latest browser to introduce a profile manager to the masses.

Mozilla announced that profile management will roll out to all Firefox users on October 14. The feature has been around since Firefox version 138.0, when it was introduced for a limited number of users.

You will be able to create multiple digital nooks for work, family, school, and personal stuff, each complete with its own logins, bookmarks, history, extensions, and themes. At the very least, you won't have to keep countless browser tabs alive for so long.

Firefox profile manager builds on existing multitasking features, such as Tab Groups, which allow you to group similar tabs. It can help organize digital work even more and help reduce data mixing and cognitive load, according to Mozilla.

"By keeping your different roles online neatly separate, you spend less mental energy juggling contexts and avoid awkward surprises (like your weekend plans popping up in a work presentation)," the browser maker said.

Mozilla stated that it designed the feature to be more accessible for users with disabilities, particularly in terms of visual design elements like avatars, colors, and naming, as well as how Firefox profiles store sensitive information, such as medical records.

Users can customize profiles by picking a different color, theme, and avatar. Mozilla claims that profile management in Firefox offers better privacy. It doesn't know the user's "age, gender, precise location, name of your profile, or other information," and will apply their 'Data Collection and Use' settings to every Firefox profile created on the device.

Note that Firefox profiles are different from multi-account containers. While profiles have a complete separation of data, multi-account containers only separate browsing data, such as cookies and logins, between different containers.

Profile management is supported on Windows, Linux, and macOS, but not on Android and iOS. Creating a new profile doesn't sign you into a Mozilla account or change sync settings. Each profile remains separate, and Firefox doesn't allow multiple profiles on the same device to sync data to the same account.
