Five retailers—HPShopping.com, HSN.com, LLBean.com and Macys.com—tied in second place in Internet Explorer testing with an availability rating of 99.99%.
HSN.com came in second place behind OfficeMax in Firefox testing at 99.99%. Amway.com and Costco.com tied in third place for December Firefox availability testing at 99.98, and three retailers (Amazon.com, OfficeDepot.com, Sears.com) tied in fifth at 99.97% availability.
The average Internet Explorer availability score among the 22 retailers measured in December was 99.88%. The same group of retailers produced an average Firefox score of 99.87%.
Availability is determined by the percentage of tests in which the retailer’s web site loads correctly.
