Clicking on urls with uppercase characters in the scheme (protocol) field
doesn't work correctly on any platform. Currently it works on Win32 because of
bug #22712 but once that is fixed Win32 will break too!

The reason for this is that if a user clicks on a HTtp://... link the networking
code tries to create a


component, this is wrong, it should be


Same thing happends with JavaScript url's and probably others.

This is XP now.

This is only partly fixed (I assume ANDREAS_URL_BRANCH landed yesterday),
HTtp://... works now but JavaScript:... doesn't work yet...

javascript urls seem to work a very different way, does anyone know where to

This patch fixes the JavaScript:... handling but I'm afraid this will brake
other things, unless protocols are *allways* lowercase?

I think this patch is safe, the only mixed case scheme I could find was
mailboxMessage and this is gone now.

I vaguely remember seeing IMAP:... urls someplace but I might be wrong, and they
could even be hadled by their own URI implementation, couldn't they. If you
the patch is OK then please go ahead and check it in...

It seems wrong for me to have nsStdURL lowercase the scheme name. We fixed the 
protocol lookup to be case insensitive. There must be another case we have to 
fix somewhere.

Warren, note that it was nsSimpleURI and not nsStdURL, but it still might be

Warren: Both has to happen. First we have to lowercase to search and find the
right component. And second we have to lowercase the scheme to move urls like
HtTp://www.mozilla.org to http://www.mozilla.org which is only cosmetical but
looks much nicer. We are already doing it in nsStdURL.cpp with the landing of

So what's missing now is to lowercase at the place where the
"javascript-protocol-handler" is searched for if something like this exists.

It's arguable whether javascript: mailboxmessage: looks nicer than JavaScript: 
or MailboxMessage:. I think we should leave the URL as typed. The 
case-insensitive comparison should happen elsewhere.

If I remove the lowercasing of the scheme in the urlparser case four of the
testcase does not work anymore. There must be more places than in nsIOService
where the search for the protocol is case sensitive.

Comment 14

I just realized that if I type "http://www.MOZILLA.Org" into the URL bar and hit
enter the url I just typed is changed to "http://www.mozilla.org". Is this due
to some of the changes that were made to fix this bug or is it unrelated to
those changes?

No, that was related to a very similar bug, now fixed, can't find the number at
the moment

Very likely a dup of 21686.

Comment 17

No, not a dup, try the testcase. Here is something different beyond lowercasing
the scheme while trying to get the right protocol-handler. To fix this we
currently have to really lowercase the scheme in the URIs. This is currently
done with Std-Urls, but not with Simple-Urls, and that's why the javascript
example fails. There must be another case of case-sensitive comparison for the
scheme, it's just not found yet.

Okay, found it. It was the securitymanager. See the attached patch to make it

Also target="_blank" seems to be currently broken, the new browser instances are
created but you can't see them. They appear briefly when you shutdown the app.
But that's another problem.

Nominating for beta1, this is nothing really serious but the fix is available
and this would make more websites work without much effort, and I bet we'll get
(more) dups of this one if it's not fixed before beta1.
