I use IE 8 almost all the time. Since I go to a wide variety of web sites, I need something which is stable (IE 8 is, having gotten rid of most of the glitches in previous versions) and which is universally compatible. I have, and sometimes use, Firefox; it's a very good browser.
I have looked at Chrome. It is also a very good browser -- with one important problem: it's put out by Google, and it may or may not track everything you do and put it into Google's cloud, but I'm not about to risk it. I'm not particularly paranoid, nor do I go to sites I wouldn't care to have other people know about, but I do not care for organisations -- government or private -- which have a track record of snooping on everything I do. (I won't use Google's search engine or maps, either, for exactly the same reason).
