I don't use Firefox as I feel itis rather primitve looking. I have worked with IE7 for a long time now, and I believe I have had it since it came out. I downloaded IE8 sometime last year. Because of one add-on, HP print clips, the browser kept crashing to the point where I couldn't use it. I took it in to Staples, and they fixed the problem, telling me what I know about it now. I downgraded to IE7 not long after.
