Who uses what? I WAS using IE8 but just made the switch to Mozilla Firefox and I'm glad I did. Much more features and add-ons to play with . I'm still trying to figure my way around it though since there's some things in totally different locations now. It definately takes some getting used to after using IE for the past 9 years
I'm on a Mac, so I haven't used IE in years. I use firefox with several add-ons. That is something that Safari is lacking. I do use Safari for when I'm testing stuff on my site (I login with a test account on that browser).
lol. IE is the least standards compliant out of all the major browsers. Every major release of IE comes with the need for new CSS hacks/tweaks developers have to learn in order to get their sites to display properly in IE as opposed to every other browser. IE is the most painful browser to develop for.
