This is happening onty in FireFox, the "L" key is encoding as a "t" and ";" key is encoding as an "f". At first I thought my keyboard was going out, but Firefox is the only program that is doing this. All other keys seem to be working properly. This question reads correctly because I wrote it in wordpad and copied it into FireFox.

Did you try to reboot the computer?

It is possible that you have switched the keyboard layout by accident by using the key sequence to rotate the layout.

Windows remembers the keyboard layout setting per application and you may have changed the keyboard layout by accident via a keyboard shortcut.

  • 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 key combination to rotate the layout is the Ctrl+Shift or Alt+Shift combination that is used in Firefox for menu items, so it is quite possible to change the layout accidentally.
  • 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
