Firefox crashes on start up

Firefox keeps crashing upon start up. Was lagging, shut it off and turned it back on and even after a reboot, I keep getting crashes. I have seen it mentioned that the Norton Toolbar seems to be the cause of it all. How do I fix this issue so I can boot my Firefox back up?

thanks for providing the crash report id. we have seen quite a number of similar reports about this issue in the last hours and this issue is likely caused by your symantec security software that is hooking into firefox (probably through a program/signature update done by them). other users reported that updating firefox in this situation helped with the crashes. you can download & install the latest firefox from https://www.mozilla.org/en-US/firefox/all/

We're sorry to hear that your Firefox seems to be crashing when you open it. Please perform the following steps to give us a crash report ID that helps us find out more about the cause of the crash.

  1. On the keyboard, press [Windows] Windows key + [R]. This should bring up a Run window that contains a text field.
  2. In that text field, type %APPDATA% and press Enter. An explorer window should open.
  3. From that explorer window, double-click on the Mozilla folder, then double-click on Firefox and then on Crash reports. Double-click on submitted.
  4. Now, you should see a list of files that contain reports. Go to View > Arrange Icons by > Modified to get the most recent files at the top of the window.
  5. Open the most recent 5 files with a text editor and copy the IDs.
  6. Paste each ID with bp- into the reply window on the forums.

Thanks in advance!

Well, this may screw me over in the end on this one but I don't typically submit crash reports. Should I submit one now just to get it to pop up?
