Firefox.exe is missing from my PC

more options

Hello. Recently I had to reset my Windows 10 because of non-stop "Not reponding" errors both offline and online. That went okay and I was able to re-connect to Firefox 96. But I was unable to find firefox.exe anywhere. My work-around was to copy my Win Apps icon to the taskbar in order to click on it.

The most relevant file I found was this one, which I guess means that FF crashed in the process of being reinstalled: firefox.exe.6892.dmp C:\Windows\old\Users\MyName\AppData\Local\CrashDumps I’m attaching an image that shows the details.

Despite not having a visible firefox.exe, FF works, except that it intermittently fails to fill in forms. When I search for Autofill Forms on the Security page, it is missing. I am a US user and via config tried pasting the autofill forms command and clicked +, but after closing FF, that function was still missing on Security.

So my question is what to do about the hidden firefox.exe and does that have anything to do with the missing autofill functionality?

In advance, thanks very much for your help.

Did you reinstall Firefox as it is likely that Firefox was no longer installed after resetting Windows ?

You can check if you have a "C:\Windows.old" folder with your Firefox personal data.

The .dmp files are Windows crash dump files. You can remove them as they only store information about the crashes you had January 13th. You can possibly check the Windows Event Viewer logs to see whether there is more info about those crashes.

Many thanks, cor-el, for your help.

I reinstalled Firefox 96 today using Mozilla's Installer and, after I rebooted, the Forms Autofill section re-appeared on the Security page! That is great because I need it many times each day. I'm glad I saved my Mozilla password and was relieved to see all my bookmarks and passwords in place after I reinstalled FF.

Yes, I found my "C:\Windows.old" folder. I didn't see any necessary FF data but that is where Windows placed various apps before resetting itself, and I can go there when I want to reinstall those apps. I had saved my current bookmarks before reinstalling FF but they were not needed. I opened the Windows Event Viewer but couldn't find anything for 1.13.22 and wouldn't have been able to understand what I was reading anyway.

--Best regards.
