Hello ashkeemash,

Thank you for posting on Mozilla Support. We value and appreciate as a user.

Please try a "Reset" as outlined below;

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information. Note: This will cause you to lose any Extensions, Open websites, and some Preferences.

To Reset Firefox do the following:

1. Go to Firefox > Help > Troubleshooting Information.
2. Click the "Reset Firefox" button.
3. Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
4. Firefox will open with all factory defaults applied.

Further information can be found in the Refresh Firefox - reset add-ons and settings article.

Did this fix your problems? Please report back to us!

Thank You!

I have done that multiple times and it still continues to happen every day.

I even reimaged my computer on tuesday hoping something would make it better, but firefox still refuses to let me use my keyboard!

Besides, resetting or uninstalling/reinstalling every day gets to be annoying.

Do you have multiple keyboard layouts installed?

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

• http://support.microsoft.com/kb/258824 - How to change your keyboard layout

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

• http://windows.microsoft.com/en-US/windows-vista/The-Language-bar-overview - The Language bar (overview)

• 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 Firefox uses for some menu items
• 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

I have no idea what you are talking about... so no??

I have never changed any keyboard settings in firefox at all.. it just simply no longer works in firefox....

i just uninstalled and reinstalled firefox for the 9th time this week... keyboard does not work at all in it.

Hello,

I have the problem too, on WIndows XP sp3. Firefox works well only if i reinstall the version 16 (french). Since the version 17, keyboard doen't respond....

All others sofwtares (IE et chrome) work perfectly ;-(
