Comment 29 for bug 25830

There's a certain point where you have to just give up and make the user do a
bit more work (in this case, save the file with .html extension and open it
locally), rather than trying to handle everything in the alert. Having `Handle
As ...' would be annoyingly incomprehensible for the majority of users who saw
this alert regularly. Already, with `View as Text', we'd be offering them more
power than any other browser I've seen.
