A Firefox browser extension by Mozilla that separates browsing into color-coded containers with isolated cookie storage, letting users run multiple accounts or identities simultaneously. It can also integrate with Mozilla VPN for per-container network privacy.
Use cases
- sign in to two accounts on the same site at once
- separate work and personal email in one browser
- keep social network logins isolated from other browsing
- prevent cross-site tracking via cookie isolation
- use different identities in color-coded tabs
- route specific containers through Mozilla VPN
When to choose
- you use Firefox and need multiple simultaneous logins on the same site
- you want to compartmentalize browsing to reduce tracking
- you want a Mozilla-maintained, widely used container solution
When to avoid
- you use Chrome, Edge, or Safari instead of Firefox
- you need full browser-level isolation rather than per-tab cookie separation
- you need anonymous browsing beyond cookie isolation
