Firefox Immediately crashing on startup
Trying to run firefox on a company computer. When launching it crashes immediately. I've tried version 3.6 as well as 4 betas. I've also tried firefox portable. The only browser that runs on company computers is IE. I can get firefox to run when booting in safemode with network support or when running it as the local administrator. My network username does have admin rights to the computer. We are running McAffee Enterprise but I have uninstalled that as a test and it still crashes. I've also run spybot and malware bytes and they have found nothing. I've also run chkdsk on C and D. D is the Windows XP profile drive. -Thanks

Unable to do so. Firefox crashes too quickly.
A person I work with found out a piece of information. If you hit 'ESC' when firefox starts it doesn't crash. But if you try to go to any webpage it crashes. Could the proxy server be causing this?
Does it help if you set the connection setting to "No proxy" ?
The crash seems to be related with setting up an HTTP channel.
You can find the connection settings in "Tools > Options > Advanced : Network : Connection"
I was able to get it to start without crashing by checking "start with a blank page". But it still crashes when typing in a website, clicking tools/add ons or when accessing about:config, about:plugins, etc. I tried setting to "No proxy" but it still crashes when typing in a website.
Did you try a clean reinstall by deleting the Firefox program folder and a new profile?
Yes, I did a clean reinstall and deleted my profile folders. Still happens. I also ran the latest version of firefox portable. Still crashes. I ran process monitor and there are some calls to the registry HKLM\SOFTWARE\Policies\Microsoft\Windows\Safer\CodeIdentifiers. I read up on it and it doesn't appear to be setup for firefox.
Some missing fonts, older versions of Google and some malicious software can cause Firefox to crash on start up. Also problems in the hardware like RAM chips can lead to a crash in Firefox. Sometimes corrupt, spoilt or older video chips can cause the Firefox browser to crash. Many a times it also crashes, when we start typing the website address. This, maybe because of a proxy server. In some instances Firefox can also crash due to some unnecessary DLL files working with Firefox. While working on media files, especially if you are using VLC Media Player and view a VPM file, it might just crash with WMP and cause Firefox to crash. Below are some of the ways of how you can solve the problem or at least minimize it. You can start by opening the Firefox browser in a safe mode or safe mode with networking. If you do this, you can probably see the extensions that might be causing up the problems. If it opens without any hassles in safe mode then go into your regular windows and immediately disable all the extensions. Once this is done, slowly one by one add them back and determine which one of them is causing the problem. Also the profile might be a problem. For this, delete the previous one and create a new profile to get the problem resolved. http://support.mozilla.com/en-US/kb/Firefox%20crashes%20when%20you%20open%20it

I uninstalled Rapport and problem fixed
In my case, we were running a slightly older version of Roboform. Installed the latest version, and Firefox fired right up. JCC San Diego, CA
