User Reviews

Users praise Container Tabs Sidebar as a reliable, highly useful add‑on that dramatically improves container tab management and is easily customized with CSS. Recurring negatives are the lack of built‑in visual controls (so users rely on CSS), some reported compatibility issues with other extensions, and feature requests such as multi‑select and showing tabs from all windows.

Pros

Reliable and well‑built — many users report it 'works perfectly' and does what they want.
Makes container tab management much easier and scales well (helpful for users with many containers); several reviewers say it should be a Firefox default.
Highly customizable via custom CSS (users successfully adjust indentation, font size, pinned‑icon size, etc.).
Widely liked and recommended — multiple enthusiastic endorsements and praise for the UX improvement.

Cons

Lacks built‑in visual/UI controls (indentation, padding, font and pinned‑icon sizing), so users must rely on custom CSS to tweak appearance.
Some compatibility problems reported with other extensions (e.g., Temporary Containers, UnloadTabs) causing unexpected behavior.
Missing a few requested features (users ask for multi‑select of tabs and the ability to show tabs from all Firefox windows).

Recent reviews

Just installed, but seems to work nicely. One improvement I'd like to see: tabs listed within each container (i.e. below the container name itself) should be indented slightly so that it is easier to see what my active containers are and what's in each of them. Alternatively, outdent the container name itself (basically the same thing).

Is Container Tabs Sidebar 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 Tabs Sidebar requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details

Risk likelihood

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.
