Cannot even open FF6 it just keeps crashing, and crashing HELP!!!

Question

I was asked last night to upgrade my FF. I downloaded the new and installed. Once it gets to actually open FF6 it crashes, it won't even open, just keeps on crashing. I want to continue to use FF, but if it keeps happening, I'm going to switch to Chrome for good !

Your above posted system details show outdated plugin(s) with known security and stability risks.
*Next Generation Java Plug-in 1.6.0_17 for Mozilla browsers
Update the [[Java]] plugin to the latest version.
*http://java.sun.com/javase/downloads/index.jsp (Java Platform: Download JRE)
Your user agent shows that you are using Firefox 3.6.9 and that the update has been successful.
'''Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.2.9) Gecko/20100824 Firefox/3.6.9 ( .NET CLR 3.5.30729)'''
If you keep having problems then do a clean reinstall of the Firefox 3.6.9 version<br />

Remove the files in the updates and updates\0 folder:<br />

You can do a clean reinstall and download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
You can skip the step to create a new profile, that is not necessary for this issue.
