Features & Capabilities

Temporary Containers is a Chrome extension designed to boost your online privacy and security by opening tabs, websites, and links in automatically managed disposable containers. These containers isolate the data that websites store — such as cookies and local storage — from each other, preventing tracking and data leakage across sessions.

The extension offers fully automatic management based on navigation targets, configurable mouse clicks, and a toolbar icon for manual control. It supports advanced features like automatic deletion of browsing history and cookies, keyboard shortcuts, and options to stay logged in on preferred websites while maintaining privacy elsewhere. Temporary Containers integrates smoothly with other privacy tools and is open source, making it a reliable choice for privacy-conscious users seeking enhanced web session isolation.

User Reviews

Temporary Containers is widely praised as a lightweight, reliable privacy boost for Firefox. Users highlight automatic isolation that limits cross-site tracking, optional permanent cookies, and automatic cleanup of containers when the last tab closes. It works well in the background and pairs nicely with Firefox’s Multi Account Container. It is open source and has community-driven maintenance, with some noting a fork after the original developer’s passing. A few users report a learning curve in settings and occasional bugs or feature requests (dark mode, shortcut to convert to permanent containers). Overall, a highly recommended privacy tool.

Pros

Strong privacy protection through automatic isolation that limits cross-site tracking and reduces fingerprinting
Automatic, background operation with minimal user effort
Lightweight and reliable performance
Open-source and community-maintained, with forks available when needed
Nice complement to Firefox Multi Account Container

Is Temporary Containers Safe?

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.

Temporary Containers requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Temporary Containers has earned a fairly good reputation and likely can be trusted.
