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] 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!

You can find more information and troubleshooting steps in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.

Followed directions to Crash reports. Two folders, both created 1/12/22: "events" - which is an empty folder and "pending" which contains 6 files, the latest one [d33aba19-0335-4fc7-bc12-d5045fc51547.extra] dated 1/12/22 11:48a.m. and the first one [bfab8815-69c8-4cb2-9a40-0d2fa0bf287a.dmp] 11:42a.m. The other four files are two ".extra" and two ".dmp" files.

Other than the two folders, there are dozens of "InstallTime...." files and only one file "submit" [not "submitted"]. That file dated 1/12/22 11:43a.m. reads: [Wed Jan 12 11:42:29 2022] Crash report submitted successfully [Wed Jan 12 11:42:51 2022] Crash report submitted successfully [Wed Jan 12 11:43:35 2022] Crash report submitted successfully

I did bring up the latest file in the 'pending' folder [[d33aba19...... noted above] and it produced text that takes up over one full page in Word, even in an 8 point font [it starts out: {"AdapterDeviceID":"0x0416","AdapterDriverVersion":"10.18.10.3355","AdapterSubsysID":"08591025","AdapterVendorID":"0x8086","Add-ons":"doh-rollout%40mozilla.org:2.0.0,formautofill%40mozilla.org:1.0.1,pictureinpicture%40mozilla.org:1.0.0,proxy ......]

I don't know which of the above you are looking for, so I will wait for another reply on whether or not to do anything. NOTE: I did re-install Firefox and have reconstructed my home page to match what I'd had, with one less row. It's working ok now so I'm not sure there's a need to mess with it, but I still don't know what caused it. Nevertheless, I appreciate your reply and directions. Thank you.

In the address box, type about:crashes<enter>. Note: If any reports do not have BP- in front of the numbers/letters, click it to submit them.

The crash report is several pages of data. We need the report numbers to see the whole report.

Using your mouse, mark the most recent 7 - 10 Submitted crash reports, and copy them. Now go to the reply box and paste them in.

Please, Do not post a screenshot ! !

Thank you for your response, Fred, but as I said in the prior reply to Seburo, there is no "submitted" folder in my .../Mozilla/Firefox/Crash reports, only an "events" folder which is empty and the "pending" folder which contained the 6 files I referred to. I went to Mozilla for crashes, then Firefox desktop and added the bp- to one of the files in my pending folder: d33aba19-0335-4fc7-bc12-d5045fc51547.dmp [without the ".dmp"]. The search came up with no results.

I appreciate the help, but apparently the crashes never got submitted. Since I've downloaded Firefox again and set up my homepage as close to what I had, I seem to be ok. User id's and passwords are kept in a separate location so I'm apparently ok for now. Nice to know the forum is out there for help; thank you again.
