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. Press the following shortcut to get a Run window: [Windows] + [R]. This should bring up a window that contains a text field.
  2. In that text field, enter %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!

First of all please try running in Firefox's safe-mode and with all plugins disabled. Holding the shift key whilst you try to start Firefox is one method of starting safemode

I suspect you have unwanted software possibly as search bars.

It will be worth looking at your Windows Control panel and the program listing, and very definitely scanning for malware.


For forum cross referencing purposes

  • Report for your CrashID bp-f5033559-582a-4438-a5f2-ae6eb2130920
    • Crash Signature: nsHTMLPluginObjElementSH::GetPluginJSObject(JSContext*, JSObject*, nsIPluginInstance*, JSObject**, JSObject**)
    • note presence of sprotector.dll (A quick web search suggests that file could be suspect)

Malware scanning

Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.

You can try these free programs to scan for malware, which work with your existing antivirus software:

Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.
