Why does Firefox crash then only type certain characters?

I've found the common factor of this error is when I'm watching a video (Youtube, for example). Firefox will sometimes crash and I can only close it via ending the process. When I then open up Firefox again, the only characters I can type are vowels, and they all have accents above them for some reason. For example, trying to type 'Mozilla' would only come out as 'óá'. Virus and malware scans yield nothing.

The crash is related to the plugin-container process.

You can check for problems caused by a recent Flash 11.3 update and possibly downgrade to Flash 11.2 or 10.3.

It is possible that you have switched the keyboard layout by accident.

  • Make sure that you have the Language bar visible on the Windows Taskbar.
  • You can do that via the right-click context menu of the Taskbar: Toolbars > Language Bar.
  • Check the keyboard language (keyboard layout) setting for the application that has focus via the icon on the Language bar.
  • You need to do that while Firefox has focus because Windows remembers the keyboard layout setting per application.
  • The default keys to rotate the layout is a combination (Ctrl+Shift or Alt+Shift) that can easily be used in Firefox to activate a menu item.
  • To avoid an unintentional switch, assign a specific key sequence (Alt/Ctrl+Shift+number) to select keyboard layouts and remove the key combination to rotate layouts (Alt+Shift or Ctrl+Shift)
  • Control Panel > Regional and Language Options > Keyboards and Languages > Change keyboards > Advanced key settings > Change key sequence
