Automatically duplicate specific cookie domains to all your multi-account containers

Download

Install

Features & Capabilities

What does it do? This plugin automatically synchronizes cookies from the 'main' Firefox container to all the other configured Firefox containers. This can be useful for instance to copy your existing login sessions to other containers.

How do I use it? On the settings page, you can specify domains you want to copy. After configuring your desired domains there, this plugin will automatically synchronize all the cookies of those domains from the default container to the other containers. It works only 'one-way': it copies cookies from the default container to the other containers, but it doesn't copy 'back' to prevent cookie conflicts.

Is Container cookie duplicator 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.

Container cookie duplicator requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.

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.

Container cookie duplicator is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
