An extension for testing what is the higher version number. 5.0a1pre or 5.0mod ? Only one way to find out with out reading any bit of info on it and doing a lot of head scratching. This extension simply used the component that Mozilla apps use for comparing versions and then tells you the result.
The extension adds an item to the tools menu to open its window.
All thanks for this extension should go to Jane Ocean whom it was made for.Download
