NEW VERSION IS ADWARE!!!
Excellent and useful for comparing prices. Now, however, it has become a pop-up adware machine: When I looked up "North Carolina" on Wikipedia, I got a drop-down ad urging me to "Buy Big Bubba's Guide to North Carolina BBQ at Buy.com!" No thank you -- I uninstalled the extension. If future versions include an option to omit the drop-down ads, I'll try it. Until then, NOBODY WANTS MORE ADVERTISING IN THEIR BROWSER, EINSTEIN!!!
