Startup Idea: Browser extension for boosting mouse speed

Startup idea to develop a browser extension for Google Chrome and Firefox that allows users to increase their mouse pointer speed, thus boosting productivity especially for people working online jobs like typing. Ideally, the solution should be free or at least not cost more than 2 dollars.

I work as a typist from my home office for various online companies. One thing that slows down my productivity is the speed of my mouse. I would appreciate software that I could download onto my computer that would make the mouse pointer faster. It would be the most convenient to create an add-on for internet browsers like Firefox or Chrome. I wouldn't be willing to pay for than 2 dollars for this, but I would prefer it to be free. This would allow me to complete my work faster.
