- Game Support Updates: The team behind the extension frequently updates the code to support the latest versions of games like Candy Crush, Bejeweled, 8 Ball Pool, and various Flash/HTML5 titles.
- Streamlined UI: The new interface is less intrusive, often sitting quietly in the toolbar until you need to activate it.
- Compatibility: It is designed to work seamlessly on the current version of Firefox Quantum and newer releases.
The Fall: Why Did Leethax Disappear?
