Cannot get Firefox to load

I have been using Firefox since i purchased my computer 9 months ago with no problems. Over the past few days I cannot get Firefox to load. When the problem began about a week ago, it was crashing on startup but I was able to work around it by restoring and opening a new tab. Now I cannot get it to load at all. I have uninstalled the program(multiple times), updated operating system and antivirus, cleaned my drive w CCleaner, deleted Mozilla folder in Program drive, restarted, did a clean install (multiple times) and still no go. When opening FF, a Mozilla Crash Reporter window opens and gives me option to Restart or Quit. Restarting does not work. It says crash report is being submitted. Saved Detailed report if that will help. It is 4 pages long - see attached images. Any ideas how to get this working again?

Some problems occur when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
  • Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see

Configure firewalls so that Firefox can access the Internet. {web link}

Comodo Firewall is up to date. I removed Mozilla Firefox and related programs from the list of trusted and recognized programs (Not sure that makes sense to me) Since I cannot open Firefox I found the submitted reports in the Submitted Crash report file for Firefox and did a screen shot that I have attached.
