When I start on a .xps file and Open with. . . and choose the Microsoft XPS file viewer, Firefox still opens and I get nowhere.


When I double-click on the file, Firefox opens, too.

Firefox wants me to save the file or browse. If I browse to the Microsoft XPS viewer (the recommended option) and select it, then a new copy of firefox opens and wants me to save or browse. Deja vu.

I have Vista, .Net 4, Firefox 3.6.10

Additional System Details

This started when...

I tried "printing" a web page with the XPS writer and wanted to open it.

Question owner

I read this link and did not see how it applied. The xps viewer is not on the list of file types in Firefox. But why does Firefox open at all? Firefox is not open when I double-click on the file. The .xps files are associated with the Microsoft xps viewer in the file associations.
