Unlike Chrome profiles, multiple Firefox containers can be used in the same window. Containers are different from profiles: https://addons.mozilla.org/en-GB/firefox/addon/multi-account-containers/ https://addons.mozilla.org/en-GB/firefox/addon/multi-account... Containers are also extensible through add-ons. For example, the following two add-ons automatically isolate Facebook and Google into separate containers to reduce the impact of their tracking: https://addons.mozilla.org/en-US/firefox/addon/facebook-container/ https://addons.mozilla.org/en-US/firefox/addon/facebook-cont... https://addons.mozilla.org/en-US/firefox/addon/google-container/ https://addons.mozilla.org/en-US/firefox/addon/google-contai... Temporary Containers goes further by allowing the user to create disposable containers either automatically or on demand: https://addons.mozilla.org/en-US/firefox/addon/temporary-containers/ https://addons.mozilla.org/en-US/firefox/addon/temporary-con... Firefox's two-tier approach (profiles and containers) to data isolation is much more flexible than Chrome's profiles. Containers handle many common use cases (e.g. logging on to the same site with multiple accounts simultaneously), and are very easy to use.
