I just wrote a note about this to the comments section but thought I would pose it here. Since V70, Firefox has been crashing on its own and leaving behind an open process. When I try to restart, it says that Firefox is already running but not responding; close the instance first.

I've been to task manager and it will not allow me to close the process. It does nothing.

My only solution thus far has been to refresh the operating system with a backup image; no solutions given me by the local community have worked yet.

This is now about the 5th time this has happened since V70 download and reloading the OS is getting pretty tiring. I'm currently on V71 and the problem has not yet been solved with the updates.

Well, usually the process closes after 1 minute.

Can you provide us crash IDs?

  1. Enter about:crashes in the Firefox address bar and press Enter. A list of Submitted/Unsubmitted Crash Reports will appear, similar to the one shown below.
  2. Copy the 5 most recent Submitted Report IDs that start with bp- and then go back to your forum question and paste those IDs into the "Post a Reply" box.

Note: If a recent Report ID does not start with bp- click on it to submit the report.

(Please don't take a screenshot of your crashes, just copy and paste the IDs. The below image is just an example of what your Firefox screen should look like.)

Thank you for your help!

Create a batch file, and place this inside; TASKKILL /T /F /IM Firefox.exe

This should make the Windows system force-close Firefox.

First, if it requires opening Firefox to do something, forget it. When the instance is running, I can't open Firefox.

Second. Tried the batch file. The instance is still running.

As nothing has changed, I'll reimage the C: drive one more time and try to get the error file loaded.

You don't have to open Firefox to get crash reports.

  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!
