User-Agent:       Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.1; WOW64; Trident/5.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0)
Build Identifier: http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk/firefox-4.0b7pre.en-US.win64-x86_64.installer.exe

Starting on the Oct 2, 2010 Minefield Build 03-Oct-2010 15:34 10M, I cannot load any webpages. It worked fine right before that build. Now, whenever I load firefox, it will load ONLY the minefield start page correctly. If I try to do any search in google, firefox crashes. If I try to go to ANY webpage - crash. 
If I use safe mode, it works properly.
I then uninstalled firefox and all personal settings. 
I re-installed it fresh with no addons and no user settings.
AGAIN, it crashes with all webpages. Works properly in safe mode.
If I set a webpage other than minefield start page or blank, it will crash immediately when trying to load the homepage.
I just re-installed the minefield version from Oct 1, 2010 and it all works perfectly. Some code from Oct 2 is incompatible with my system. The problem started with the very early morning Oct 2 win x86-64bit build!


I will give a couple windows 7 crash reports below.

Reproducible: Always

Steps to Reproduce:
1. Load firefox (not in safe mode)
2. Try to load a webpage

Actual Results:  
A window labeled "Minefield" pops up saying:
Minefield has stopped working
Windows can check online for a solution
 to the problem.
Two choices:
Check onine for a solution and close the program

Expected Results:  
Loaded the webpage properly. It works if I use "Safe Mode". I don't know what the difference between "Safe Mode" which works. BUT, with NO ADDONS and NO USER SETTINGS/ Totally Fresh Install - it does not load any webpages. Oct 1 builds and before work fine though.

All the crashes give the same problem details. Every crash has the exact same info as given in the "Actual Results" above... This is a totally fresh install of minefield with any 64bit build from Oct 2 and later. I have no addons and no user settings. This was a relatively fresh Windows 7 build. I don't have much other software loaded on the system - Microsoft Office 2010?

I went back to an Oct 1 build of minefield because I can't use anything after that.

I believe the exact build the crashing STARTED on was:
http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/2010-10-02-01-mozilla-central/firefox-4.0b7pre.en-US.win64-x86_64.installer.exe

The Oct 3 build has the same problem.

The Oct 1 build before that works well.
