Start Designing For Firefox

I was just reading the excellent MarketingSherpa site and they’re saying “100 million consumers have downloaded the Firefox Web browser in the past year. If you market to a cutting-edge demographic, up to 35% of your traffic could be from Firefox users.”
Lots of things break in Firefox (i.e. shopping carts) so it might be time to check back on old site designs and offer clients a rebuild based on Firefox issues.
