When you use Firefox, all your data such as bookmarks, passwords, and settings are stored in a “profile.” Creating multiple profiles allows you to keep separate browsing data, themes, or settings for different purposes, such as work and personal use. This guide walks you through the steps to create, customize, and manage Firefox profiles.

FAQs
Is this feature available on Android or iOS?
No, the profiles feature is currently not supported on Android or iOS.
Does creating a new profile log me into an account or affect my sync settings?
No, creating or managing profiles does not log you into a Mozilla account or change any sync settings. Sync remains separate, and profiles allow you to set up different browsing environments without linking them automatically to an account.
Will switching profiles mix my data if I’m signed into a Mozilla account?
No, switching profiles won’t merge or mix your data. Each profile keeps separate browsing data, bookmarks, and settings. You can only use a Mozilla account on one profile per device, so you can switch between profiles without worrying about data merging.
Should I back up my profiles?
The best way to protect your profile data is by creating a Mozilla account for each profile. Sync automatically protects your data across devices, ensuring easy access whenever you need it.
