User-Agent:       Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.04506.30; .NET CLR 3.0.04506.648; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729)

If you use Firefox with a proxy and have multiple tabs as your home page then, upon being started, Firefox will put up a proxy credentials prompt for every single tab.  These promtps appear at random places on the screen (two appear in one place, one appears in the centre of Firefox) and are *very* annoying.

As I have only one proxy set in Firefox it should only be prompting me with a single Proxy credentials dialog.  

Additionally when promting for a password the Firefox icon in the Windows taskbar flashes no matter what settings I have made in the O/S (using TweakUI I have it set to "prevent applications from stealing focus" and "Flash taskbar button 1 times").  

When prompting for Proxy credentials Firefox should present one, and only one dialogue,and should respect my "no flashing icons" settings.

Reproducible: Always

Steps to Reproduce:
1. Set up proxy which requires authentication
2. Set up multiple tabs for home page.
3. Start Firefox.

Actual Results:  
Get multiple prompts for authentication - one for each tab.

Expected Results:  
You should only be presented ith one authentication dialogue.

Prompted me once and *not* cause its taskar icon to flash (respect my OS settings)
