This Windows 10 file is Crashing : ucrtbase.dll Your Shutting Firefox down so it is not actually a Crash it is a Kill.

Please Search for Event Viewer and Search for same time as the Crashes. Or next time go there and look.

It is Microsoft Patch Tuesday today, Please Patch and reboot.

This is the Windows 10 Registry and System Files fix, Note : may download new files. 1)Use the Windows key + X keyboard shortcut to open the Power User menu and select Command Prompt (Admin). 2)Type Copy/Paste the following command and press Enter: 3)DISM /Online /Cleanup-Image /RestoreHealth 4)Reboot

Please let us know if this solved your issue or if need further assistance.

Note that these are shutdown hangs where Firefox takes too long to close down properly and a crash is forced.

You can create a new profile to test if your current profile is causing the problem.

See "Creating a profile":

• https://support.mozilla.org/en-US/kb/profile-manager-create-and-remove-firefox-profiles
• http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Profile_issues

If the new profile works then you can transfer files from a previously used profile to the new profile, but be cautious not to copy corrupted files to avoid carrying over problems.

@cor-el : i've initialized FF, i've uninstalled and reinstalled FF, i've deleted and created new profiles, the problem is identical

@FredMcD : I still need further assistance. I've installed Microsoft Patch Tuesday batch. i've executed the DISM command, still no change in my problem. You're right i actually killed FF because the tabs and FF wouldn't terminate by itself. For your information these problems do not occur with MS Edge I submitted 10 new crashes, all done while in Safe Mode,

Attention Sumo's there are 15 related bug reports

ucrtbase.dll = Windows

ntdll.dll = Microsoft

See if this helps; https://answers.microsoft.com/en-us/windows/forum/windows_7-windows_programs/programs-close-faulting-module-ntdlldll/54aaaec5-2b53-4e9f-b9a7-b7889a1cd4b6?auth=1

i didn't find any useful information to the problem i'm having. I don't have nvidia, i did a sfc /scannow with no problems listed. I didn't copy my ntdll.dll off my laptop pc to the pc where i'm having problems, but if its necessary i will. It seems to me this is a windows problem and not a FF one. Am i correct? Why am i having this problem on FF and not MS Edge ?

any updates ?

I called for more help.

i've got to be a real firefox fan to endure this problem every day since the month of May !!

the problem is fixed after the MS update KB4462933. FF no longer hangs after opening a new TAB. Thanx for the help

That's good to hear. Please flag your last post as Solved Problem so others will know.
