EXTREMELY helpful Rated 5 out of 5 stars

I am a web designer and this is an AMAZING tool for me. I have had lots of trouble because I always use the best browser out there, Mozilla Firefox, NOT IE, because they are the worst and I hate them, and sometimes I find my results not the way I wanted them in IE. With this tool, I can easily switch to IE and back, to quickly and effectively correct my errors. THANK YOU!
