What's on your computer may determine what's in your wallet.  The browser you use could impact the price of a product or service purchased online. 

If you're looking for a lower auto interest rate from money lender CapitalOne for example;  having Google Chrome as your web browser could provide a lower overall cost while using Firefox may generate a higher rate.  

According to some online reports, a reader on the popular consumer watchdog website The Consumerist, wrote in to complain about discrimination by browser after placing an online order for a new electric car, the Nissan Leaf.  

A week before he placed the order, CapitalOne sent reader Devin an email offering him an interest rate of 3.10 percent. After placing the order and receiving a final price, he decided to re-check his interest rate.  At that point, Devin learned that his rate had changed to 3.5 percent.  

Devin deduced that the switch resulted from using Firefox; his default browser and he decided to experiment. After downloading fresh browsers, Devin discovered that by using different browsers, his interest rates varied.

"I tried to use their little payment calculator, but the Flash-based widget wouldn't work properly in the Firefox Beta so I loaded up Safari to try," Devin explained.

The web browser Safari generated a 2.7 percent interest rate, while Opera garnered him a rate of 3.1 percent and Google Chrome earned him an interest rate of just 2.3 percent.
