I use chrome mostly though at work I have to use both chrome and internet explorer. It's annoying most of our applications only work on IE and won't allow me to tab them in to one browser window because of how old the version of IE is. I'd like for them to allow me to run all my programs in one or two windows instead of like 10 especially since the pc's at work suck and slow down so much. I do use IE if I need a backup browser though mostly because if it doesn't work in Chrome but works in IE it's definitely something I can fix.
