More:Mozilla accuses Finfisher makers of 'hiding' under name
The Mozilla Foundation has accused UK software group Gamma International of falsely associating one of its products with the Firefox name.
Finfisher is legitimate surveillance software thought to be used by governments to covertly obtain data.
It is installed unknowingly by its target computer user, often by disguising itself as an update to a well known programme such as Firefox.
