## Review summary

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).
