User Reviews
Pros
- Effectively colorizes tabs and helps visually distinguish tab trees/groups.
- Multiple users report it works well and meets their needs.
- Appealing, colorful visuals that users describe as cute; offers some color customization.
Cons
- Colors are often too bright with poor contrast on dark modes; tab text can become unreadable — users want brightness/contrast controls.
- Stability and compatibility problems: several users report the add‑on doesn’t work, crashes, or requires restarting the browser; some report it fails on Linux/CentOS.
- Limited control over coloring: lacks reliable per‑domain or selective coloring and options like inheriting parent/tree colors; users request finer control.
