People used Firefox because their nerd friend or family member helped them download and install it. We got to 100 million downloads almost exclusively on word of mouth. It's not enough to have a better product, people have to learn about it and we did that with SpreadFirefox and other efforts I helped initiate so I'm very familiar with this. You don't have to trust my appeal to my own authority here, but I doubt you've got anyone closer to Firefox's early growth than me so maybe worth listening.
