It’s official – the Guinness World Records has bestowed Firefox 3 as the most downloaded software in 24 hours! From June 17 to 18, the browser was downloaded over 8 million times. Weeks before Firefox 3 was ready, Mozilla rallied Firefox users to download the browser on June 17 Download Day and gathered 1.7 million pledges. Now, the total number of downloads worldwide stands at 28 million, and Singapore contributed about 130k downloads. Not too bad a number, considering that the numbers from our bigger neighbours aren’t very much bigger. With Firefox becoming more popular, I’m still baffled by the fact that some media websites still don’t work properly in the browser. Cross-browser testing as part of the 101 of web development somehow just hasn’t sunk in.
