229702 - Should not have "Save Link As" option on links whose protocols we can't handle

Status: NEW

(SeaMonkey :: UI Design, defect)

Description

[Boris Zbarsky [:bzbarsky]]

BUILD: any recent-ish windows build (using 2003-12-28-17 here). 

STEPS TO REPRODUCE:

1)  Make sure you have Windows Media Player installed
2)  Find a link to an mms file;  mms://this_is_such_a_link
3)  Right click on the link
4)  Select "save link as"
5)  Pick a spot to save to

EXPECTED RESULTS:  Good question!

ACTUAL RESULTS:  Windows Media Player opens and plays the movie (if it's a link
to a real movie)

SUGGESTED RESOLUTION:
I suggest we not show "Save link as" in the context menu for links that we can't
save.  The problem is determining such links.   I guess getting the protocol
handler for the protocol off the IOService and then seeing whether it QIs to
nsIExternalProtocolHandler would work.  darin, does that seem reasonable?

Scott, I'm ccing you because it looks like tbird forked nsContextMenu.js so
whatever we do here may need porting over there...

Well, bugzilla didn't linkify the link in steps to reproduce... but it did
linkify the one in the URL field, so use that one to test.  ;)

BTW, IE5 pops up a "Download could not complete!" error :-)

That's vastly preferable to what we do.. ;)
