496718 - CIDR notation not respected for proxy ignore settings

Status: NEW

(Core :: Networking: Proxy, defect, P5)

User-Agent:       Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.10) Gecko/2009042523 Ubuntu/9.04 (jaunty) Firefox/3.0.10
Build Identifier: Mozilla/5.0 (X11; U; Linux x86_64; en-US; rv:1.9.0.10) Gecko/2009042523 Ubuntu/9.04 (jaunty) Firefox/3.0.10

In gnome's network proxy settings, there are a few "ignore hosts" entries.  By default on Ubuntu anyway, there are 3.  localhost, *.local, and 127.0.0.0/8

The problem is that 127.0.0.0/8 isn't respected, so 127.0.0.1 for example is not an ignored host as it should be.

Reproducible: Always

Steps to Reproduce:
1. Must have a proxy set up in Gnome, make sure there's not an specific entry for 127.0.0.1 but that there's a cidr-style 127.0.0.0/8
2. Try http://127.0.0.1/ in the browser


Actual Results:  
Firefox uses a proxy and I can never hit my local site

Expected Results:  
Firefox should ignore 127.0.0.1 because of the ignore entry 127.0.0.0/8

If 127.0.0.1 is added explicitly to the gnome proxy settings, 127.0.0.1 is ignored properly.

Strangely, the cidr notation works properly in Firefox's own proxy preference dialog, but when it's set up to use the system settings, the cidr notation is not respected.

I confirm this bug still exists for IceWeasel 9.0.1, when parsing $no_proxy env variable.
