It is so wonderful that I can't imagine any more words to praise it.
But there are some issues that need to be addressed.
1. Can I disable the identity TAB while using it?
2. Can the color scheme of toolbar ICONS be more similar and more user-friendly than the ICONS in firefox?
3. In the "Tree Style Tab" sidebar, can I get a clean right-click menu that only contains close, mute, lock, and the menu items I checked in the Settings, and optional or does not include submenus created by other extensions?
