User Reviews
Pros
- Opens external links and bookmarks in a specific Firefox container (ext+container)
- Bookmark-based and scriptable container routing for automation
- Option to suppress per-link prompts by enabling a config flag in about:config (network.protocol-handler.external.ext+container)
- Useful for multi-account workflows and separating site access within the same browser
Cons
- Firefox protocol-handler warnings/prompt annoyances after recent updates
- Windows users report protocol handling compatibility issues (reliability problems on Windows)
- Activation/setup issues on older Firefox versions (possible inability to activate)
- Bookmark creation/saving for ext+container can be unclear or non-intuitive
- UX quirks such as the bookmark path affecting the page icon (disappears)

I wonder why basic functionality like this aren't implemented in containers by mozilla! Great work, with additional option 'network.protocol-handler.external.ext+container' set to true in about:config which removes prompt on every link opening with this extension. Allows to create a bookmarks which opens in specific containers. Thank you!

Is Open external links in a container 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.
Open external links in a container does not require any sensitive permissions.
