Account Per Container

Account Per Container is a Firefox extension designed to help you manage multiple online accounts by associating different usernames with different browser containers. It ensures you don't confuse accounts by remembering which username is used in each container, streamlining logins across various websites.

Unlike password managers, this extension does not store any passwords — only usernames are saved locally or optionally synced with Firefox Sync. It supports HTTPS sites and provides an easy setup process through its interface, allowing you to add, view, or remove username rules per container seamlessly. With a strong privacy focus, it collects no personal data beyond the usernames you enter, guaranteeing a secure and private browsing experience while keeping your online identities organized.
