Comment 53 for bug 25830

I'd like to see the "View As Text" option for mime types other than text/*. For
example, right now I can view C source files but not TCL source files. I
checked, and .c files are sent with a mime-type of text/plain, while .tcl files
are sent with a mime-type of application/x-tcl. Don't ask me why... However,
since both are actually plain text, it'd be nice to be able to view both in Mozilla.

Someone suggested forking an external viewer/editor. This does work (I tried it
for the TCL files), but it isn't as nice as seamlessly viewing in Mozilla along
with other file types.
