Crash ID: bp-0b55d86e-8a82-473d-a53c-5d6d12150304

Can't start, even in safe mode. A window shows up and it keeps going to the Mozilla Crash Reporter.

Performed all the steps in https://support.mozilla.org/en-US/kb/firefox-keeps-crashing-startup, including removing program and all Firefox %apdata% folders.

The crash report flagged these programs;

igd10umd32.dll = Intel(R) Graphics Technology

IPSEng32.dll = Symantec Intrusion Detection

IPSLdr32.dll = Symantec Intrusion Detection


Check for updates to the graphics.

Run the Symantec updater. Also, open the options of your protection programs, and tell them to leave the browsers alone.

  • 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
