There are a lot of cookie manager extensions for Firefox, and some of them allow to import cookies from the clipboard or from a file. I believe that I know nearly all of them.
However, I am using multiple Firefox installations on different PCs with Multi Account ContainersMulti Account Containers and Temporary ContainersTemporary Containers. From time to time, I would like to export all cookies from a certain container into a file aton one PC and import these cookies into a certain container aton another PC.
The former (export cookies from a certain container) is a no-brainer since some extensions are able to do that out of the box (e.g., Cookie Quick ManagerCookie Quick Manager). But I couldn't find a solution for the latter (import cookies into a certain container).
Does anybody know of an extension that can do this?
