Hi Suraj, thanks for your response. I agree with a lot of things you say, especially about Firefox reaching its apex and gaining popularity with 'other age groups'. I hope this happens, and soon. I have followed the Linux open-source development for more than 10 years. I've been working with IE since 1996 (6 years before anyone thought of Firefox). I've witnessed a lot before I grew 'skeptical'. I do not work for Microsoft, and personally prefer Firefox over IE.
I apologize if I offended you, but I've been rather cold about open source development, including that of Firefox. The compatibility of a browser and its working makes a direct impact on my industry and on my work. Scores of frustrated eLearning LMS developers (and end users) will tell you why IE is the only choice they have. You'll witness similar arguments from banking/payment gateway developers. Review any banking/eLearning browser statistics, and you'll know.
I just hope Firefox (and similar entities) present a good solid competition for Microsoft. This will ensure a good product range for developers and users, and make them available at reasonable prices. IE's popularity, though helped by default installations on Windows PCs, is and remains undisputed in any business environment. In fact, 'IE coming default installed on 90% of PCs' is not gonna change for a long time. It's what happens when a giant with a US $ 300 billion market capitalization supports a flagship browser. Though I may not be a skeptic, I'm not a believer either.
