Status: RESOLVED WORKSFORME

(Toolkit :: Downloads API, defect)

Description

[Gary Bentley]

User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; SIK30)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.6) Gecko/20040206 Firefox/0.8

If you browse to a localhost URL but there is no server available on the 
localhost to respond to the request nothing happens.  That is the page that is 
currently displayed in the browser is not changed and no popup window is shown 
to indicate that the server cannot be reached.

In FireBird I seem to remember that a popup window was shown.  Even IE has it's 
very nasty "page cannot be displayed" page.

Reproducible: Always
Steps to Reproduce:
1. Browse to http://www.google.com
2. Ensure that there is no server on the local host that can responed to the 
request.
3. Browse to http://localhost:8080

Actual Results:  
Nothing that's the trouble ;)

Expected Results:  
Provide a popup window to indicate that the requested URL is unreachable, with 
an optional message indicating why the URL is unreachable.  i.e. bad request, 
server unavailable and so on...

Works for me both with XUL error page on and off:

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7b) Gecko/20040327
Firefox/0.8.0+

Could you retry with a nightly please, there was definitely a change in this
area recently:

Reporter, please only reopen if you can reproduce with a recent nightly build
and a clean profile.
