I’ve been using Firefox Containers for years through Mozilla’s Multi-Account Containers extension.[1] Now that container management is available directly in Firefox, I’d prefer to use the native implementation if possible.
Mozilla notes that the extension still adds some functionality:
“Installing the Multi-Account Containers extension developed by Mozilla provides a few benefits on top of the native container functionality like site-specific container assignments, syncing across devices, and integration with Mozilla VPN or your own proxy.”[2]
I don’t currently need any of those additional features, so the native version would probably be enough for me. What I haven’t been able to figure out is how to switch without losing my existing setup. Are the containers created by the extension already shared with Firefox’s native container manager, or is there some migration process? Can I safely uninstall the extension and keep my existing containers, names, colors, icons, cookies, and active sessions?
