724459 - Edit to add query string to localhost URI fails where same edit to http://localhost succeeds

Status: RESOLVED INCOMPLETE

(Firefox :: Address Bar, defect)

Description

[David Woldrich]

User Agent: Mozilla/5.0 (Windows NT 5.1; rv:10.0) Gecko/20100101 Firefox/10.0
Build ID: 20120129021758

Steps to reproduce:

in my location bar, URL was listed as 

localhost:8085

I wanted to add a query string, so I edited the location to read

localhost:8085?shell


Actual results:

Firefox failed with a message box Alert:  

"Firefox doesn't know how to open this address, because the protocol (localhost) isn't associated with any program."

(Please notice the use of contractions in the message string and the odd comma after 'address'.  This text for this alert could probably use an edit.)


Expected results:

It should have parsed the string as I intended it to.

There are two workaround edits I have found that do not error out when adding a query string to "localhost:8085":

http://localhost:8085?shell
localhost:8085/?shell

What's interesting is, when I use "http://localhost:8085?shell", I see the location mutate twice.  First it changes to "localhost:8085?shell" (all black text).  And then after the page loads, it changes to "localhost:8085/?shell" (where localhost is black and :8085/?shell is grey).

It may be that "localhost:8085?shell" fails because that add-slash code that makes the localhost URL parse correctly run in the first phase immediately after the user hits enter.

confirming with FF10

http://localhost:8085?shell is a valid URL per
http://tools.ietf.org/html/rfc3986#section-3.2

>The authority component is preceded by a double slash ("//") and is
>terminated by the next slash ("/"), question mark ("?"), or number
>sign ("#") character, or by the end of the URI.

I suspect that my pro blem is caused by exactly the same issue. 

I build websites on localhost host in a folder that has a spaces in the name. When using Firefox without any changes (from the default, i.e. no config changes, and no addons), I have a problem. 

The address bar shows:
localhost

I then add "folder with spaces" like:
localhost/folder with spaces

Rather than loading
http://localhost/folder with spaces
like expected, it loads a Google search... This is very very annoying.  (In my main profile I have the http:// showing all the damn time.)

If I type in: 
http://localhost/folder with spaces
it loads correctly. And if I then just press enter in address bar, it doesn't reload that page (like you'd bloody well expect), but goes to the default search engine again. Because it's removing the http:// because somebody thought it was too confusing or something...

I guess I should say: This is happening on Ubuntu Linux, with the default Ubuntu Linux build of Firefox, and has been happening for many versions now, including 27.0.1 which is the current version.

I only get this by setting keyword.enabled to false. By default, a search is performed.
