Keep container cookies Firefox

Keep container cookies

A firefox extension to save and restore cookies in non-default containers.

Features & Capabilities

Saves all container tab's cookies. They will then be restored upon startup.

I use this to keep logins in containers, but have the default container wipe cookies when I shut down Firefox. Because Firefox doesn't have an option to wipe only the default container.

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Keep container cookies requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
