"I don't want to download the files; I just want to browse them."

My mistake. I misread your OP. I think I must have focussed on:

"... want to download the file and display it in some other application rather than just displaying it."

You were saying what your browsers want; not what you want.

I think I've been gazing at far too many weird looking Unicode glyphs today. Time to rest my tired eyes.
