Use it safely
Containers are not anonymizers. Cookies and login sessions in the container are not synchronized to other devices using Firefox Sync, so you must log in on each device.
Turn it off or restore settings
When you do not use Mozilla Firefox, first stop the resident, automatic startup, and synchronization settings in the app. Restore the association from Windows' [Default Apps], check the location of the created data, and then uninstall it.
- Complete or explicitly stop ongoing processing and close the creation
- Cancel automatic startup, monitoring, synchronization, and browser linkage in app settings
- Export the necessary settings and data and delete them from the OS application management
Limitations and requirements
- Containers are not anonymizers. Cookies and login sessions in the container are not synchronized to other devices using Firefox Sync, so you must log in on each device.
Frequently asked questions
Are cookies also synced?
No. In-container cookies and login status are created for each device.
