Rated 4 out of 5 stars

Great little addon, does exactly what I need. Is it possible for you to create an option to disabled "Open in default Win32 Application"

This review is for a previous version of the add-on (3.0.2.1-signed). 

I didn't want to clutter the extension with prefs of any kind. Actually, that radio button is sort of a feature, so you can open any file without having to make Firefox know the actual application yet...

I'm gonna investigate for some feedback about that, though.
