Task: Question Answering
Input (English): Context: Like it or not , this represents a niche market . Unless they have a master plan , like pushing it to all the IE users with Google Desktop and Toolbar installed , I wonder how they will take share from IE without cannibalizing Firefox , in which Google is heavily invested .

Question: What can disturb the internet browser market ?
Output (English): Computer users changing their preferences.
