I think this has recently been broken again. I've recently upgraded to 
Firefox 29.0, and now when I paste in line-broken URLs to the location bar, 
the line-breaks show up as spaces, which means they're then no longer the 
right URL

eg if you copy a URL into the address bar:
http://example.com/line-wrapped-
url/

It now no longer comes through as "http://example.com/line-wrapped-url/", as 
this bug fixed it to, but is instead "http://example.com/line-wrapped- url/" 
(which isn't the same URL so doesn't get you to the right place)

>>>

This correctly worked before. It was even fixed before, in bug 513648. I'm not sure when it broke this time.
I'm seeing this on x86 - Win 7 (Firefox v30 beta channel).

I get http://example.com/line-wrapped-url/ in the location bar.
I can reproduce the problem on windows7 but not on Ubuntu12.04.
So, this seems happens on Windows and MacOSX.

And, after I performed the customize mode once, the problem is gone.

This regression range doesn't make sense if 29 is unaffected. Even if it did, this is unrelated to the australis merge (which was in november 2013).

Bug 513648 was about pasting in the content of the window with the middlemouseclick (which navigates by default on Linux) and not about the URL bar, which bug 513648 comment #0 explicitly says worked at the time.

I mean this is Australis related bug. So I add 939862.

Any way, The regression range is correct.
Something changed in that was 29beta/aurora.
Firefox29 is also affected.

I have literally 0 ideas on how this could cause this feature to break. Ehsan, AFAICT the editor newline=somethingorother thing is breaking here. Do you have cycles to investigate why that is?

Why do you think this is editor related?  The code for the newline handling in the editor has not changed at least in the past couple of years.  Also, comment 9 and comment 3 clearly pinpoint this to the customize mode.
Flags: needinfo?(ehsan)
WORKAROUND #1
Toggle customize mode once.

WORKAROUND #2
Evaluate the following code in Browser Console.

gURLBar.parentNode.replaceChild(gURLBar, gURLBar);

Because the problem occurs when the user /doesn't/ enter customize mode? The only thing even vaguely related to customize mode is that doing any kind of DOM manipulation that reinserts the node (like entering customize mode) makes things work, but considering that even a node.parentNode.replaceChild(node, node) does that, that hardly has anything to do with customize mode...

I think it's editor related because nothing is touching that attribute (newline) and yet it doesn't actually work. The editor is what's stripping the newlines here, and that's what isn't happening. Considering that re-inserting the node makes everything work again, it seems logical that the issue here has to do with /something/ breaking editor initialization/configuration in a way that means this attribute no longer does what it's meant to do. Because the implementation of the newline attribute is all in C++, I have no idea where to even start debugging, and because you effectively own editor these days, I'm asking you if you can help us out here.
Flags: needinfo?(ehsan)
Gijs, I'm _trying_ to help here.

Comment 12 actually suggests that this might be a reframing problem.  I seem to remember that we used to set the newline handling behavior somewhere in urlbarBindings.xml but I can't find it any more.  Looking for the callers of http://mxr.mozilla.org/mozilla-central/source/toolkit/content/widgets/textbox.xml#132, I can only see one test that is calling it!  Who's responsible to set the newline handling mode on the URL bar these days?
Flags: needinfo?(ehsan)
I swear I debugged this issue once!  What's happening is that mNewlineHandling is set by the XBL constructor for the <textbox> element, and then we reinit the editor and reset the value from the pref (which is "replace with space").  Presumably the reason why this is triggered by Australis is that it changes when/if we reinit the editor.

And succeeding, I think! :-)

I apologize if I came across harsh earlier. I should have included more information in the initial needinfo, and more understanding later when it wasn't immediately obvious why I needinfo'd you. My fault. Thanks a lot for diving in. :-)

Now, if adding some extra spaces at the end of the first line and at the beginning of the second line, the result is still "http://example.com/line-wrapped-url/". I think it should be "http://example.com/line-wrapped-     url/"

That is expected.  The buggy behavior was replacing a newline character with a space character.  Spaces in the original string should be left untouhced, which seems to be what you're seeing.
Flags: needinfo?(ehsan)
My understanding is that spaces that are contiguous with line breaks are stripped, and that that is the intended behavior.

The two comments above are opposite. What is the intended behavior?

After this patch, I see the new behavior is what Jesse said, ie., spaces in first line plus the line-break and spaces at the beginning of second line are both stripped.

Exemplified:

According to Ehsan and Paul,

should turn to

(where • = space)

But after the path, I see:

converted to

This is actually what I was saying it's not working

Looks inconsistent to me, other spaces (that aren't contiguous with line breaks) are kept.

Like Jesse said, the default behavior is "stripsurroundingwhitespace", so the behavior that you see is expected.  FWIW I did verify this bug when I fixed it, we don't really need to spend more time on it.  :-)
