On my sites I use:
target="_tab" since most browsers now know that people want something to open on new tabs instead of new windows. I can confirm that this works for me in the following web browsers:
Opera , Chrome , Flock , Firefox and Maxthon .
However, it still does not work on any version of Internet Explorer, including their new beta version: 9. Apparently, this boils down to "User Preferences" with Internet Explorer.
Determining which application opens a particular file format is currently and should always be provided to the user, not the developer *.
