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] The image "Windows key" does not exist. + [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!

since crashing with open tabs, each time I press Firefox to open the crash reporter pops up and it will not open. I have tried safe mode and the same happened, and I have removed Firefox and re-installed and it still won't open

I am having to use IE or Edge and not liking it !

I have done the same - Click Firefox ICON, immediately goes to Crash Reporter , then after several tries QUIT. Have uninstalled and installed Crash ID: bp-39783512-d535-4f75-8287-9f0a12160402 Crash ID: bp-7c811505-ab24-410a-b35e-1e6f22160402 Crash ID: bp-b94f4cb6-4eab-47c4-9d4a-9dc232160402 Crash ID: bp-d52eb4bd-33f1-42b7-9e55-ae7e42160402 Crash ID: bp-d0395849-c70f-48aa-acdf-a801e2160402
