User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.5; en-US; rv:1.9.0.10) Gecko/2009042315 Firefox/3.0.10
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X 10.5; en-US; rv:1.9.0.10) Gecko/2009042315 Firefox/3.0.10

I'm getting the following Error Console message on a permanent basis pointing to the nsBrowserContentHandler.js component:

Error: Warning: unrecognized command line flag -foreground
Source File: file:///Applications/Firefox.app/Contents/MacOS/components/nsBrowserContentHandler.js            Line:713 (see attached source below)

I have tried disabling all Add-ons (see below) and have re-installed FireFox to no avail. I'm running FF version 3.0.10 on PPC Mac OSX 10.5.6. The issue is permanent and shows up on all files parsed even no files.

Reproducible: Always

Steps to Reproduce:
1.Launch FireFox
2.Select: Tools - Error Console
3.Select: Errors
Actual Results:  
Error Console displays message outlined above.

Expected Results:  
Error Console Messages should not refer to FireFox components? (I'm no expert)

I checked where the error lands on in my build. It's on this line

Error: Warning: unrecognized command line flag -foreground

Source File: file:///Users/mozilla/ff-dbg-shiretoko/dist/ShiretokoDebug.app/Contents/MacOS/components/nsBrowserContentHandler.js
Line: 708

Components.utils.reportError("Warning: unrecognized command line flag " + curarg + "\n");

Still seeing on 3.6.

It's happening because of http://mxr.mozilla.org/mozilla-central/source/toolkit/xre/nsCommandLineServiceMac.cpp#171

It was added long ago in bug 345057. CC'ing Mark who wrote the code & moving to right component.
