MacMac - Multi Account Manager от oxcl

MacMac is a multi-account container manager for Firefox

Multiple accounts. Same website. Fully isolated.

MacMac lets you create and switch between multiple accounts on the same website. Each account runs in its own container with separate cookies, sessions, and data.

unlike the official mozilla addon for extensions, MacMac will automatically switch to the right container when you visit websites so you don't have to manually switch between them
