Before I got my Mac I was a die hard firefox user. I used firefox for almost 99% of my web browsing. Even before I was a firefox user I was a die hard keyboarder (I hate slowing myself down by using a mouse). When I got my Mac Book Pro in 2007 for the Webmaster Jam Session, I soon found that maybe safari was a better choice for my keyboarding habbits. While firefox (in many ways) works the same on all operating systems, one little thing drives me crazy about it on the mac. It skips over several form elements while using the tab key (Drop Downs, checkboxes, radio buttons). This is what drove me to use Safari.
