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!

Firefox is open for sometime, i am checking email, opening a program on my desktop, for 5-30 min. Then, all of a sudden the window closes, and right away a new window opens No crash report comes up, and the new window does not have any of the programs I was looking at. I run Malwarebytes often, check Win Updates, check add-on updates, etc.

That is a problem with the Java plugin (npjp2.dll)

• Firefox 30.0 Crash Report [@ RtlpWaitOnCriticalSection | EtwEventEnabled | npjp2.dll@0x1681 ]

What is the current setting of the Java plugin?
