Hi!

Every 10-15 days Firefox crashes on one of the machines.

The only error I have is the "No mapping between account names and security IDs was done" in the Event Viewer at the time of the crash.

Firefox and the system fully up to date. The system exhibits no other issues.

Windows 11 Pro, no domain, crashes happen on multiple accounts on that machine.

The user is not signed in at the time of the crash. They have been using the same add-ons for years, but just to rule it out, Troubleshooting mode was attempted to no avail.

AV has been completely removed temporarily to avoid any conflicts.

We're sorry to hear that Firefox is crashing. In order to assist you better, please follow the steps below to provide us crash IDs to help us learn more about your crash.

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

  1. Enter about:crashes in the Firefox address bar and press Enter. A list of Submitted (and Unsubmitted, if any) 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.)

I cannot see them unfortunately as https://crash-stats.mozilla.org website does not open, can you confirm the URL?

I was able to open the files. Looks like unchecky_bg.exe is the cause. The user does have Unchecky installed.
