Bottom LineThe latest version of first the world's leading browser delivers category-leading security and adds some pretty slick browsing aids, such as WebSlices and Accelerators. It defaults to a more standards-compliant mode, but still offers a backward compatibility button. A predictive address bar brings it closer to Firefox, but the lack of a download manager and robust extension ecosystem hold the browser back.
ProsAddress bar offers Autocomplete. Tabs have color-coded groupings, crash isolation. InPrivate browsing. Flexible search. Easy access to Web content. IE7-compatible view. Better security, performance. Crash recovery. Fast startup.
Apparently Firefox is now the standard. Who knew?!
