I prefer to use Opera for several reasons. Many attacks depend on features, some of which are know to users and some not, of internet Explorer.
Opera does actually run faster in many circumstances.
Multiple windows within the interface. The zoom control The ability to increase the size of the page on view, or to shrink a picture to get it all onto one screen, or part of one while reading text in another window is one I treasure. Using two windows, displaying all the links from one in the other, seriatim. It works well for complex sites that I want to flick through and then review off line. Very well, in fact.
