Do you have a dictionary installed and selected?

You can see which dictionary is selected if you right-click in a text area and open the Languages submenu.

• Open the "Add Dictionaries" link to install a dictionary if you do not have one.
• Make sure that [X] "Check Spelling" in the right-click context menu is check-marked.

You can enable or disable spell checking globally:

• Tools > Options > Advanced : General: Browsing: "Check my spelling as I type"

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

See:

• http://windows.microsoft.com/en-US/windows7/The-Language-bar-overview The Language bar (overview)

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

Hello, I have just checked all of the above information and can't seem to get the language bar to come up for FireFox. As I have stated this problem only happens with FireFox and none of the other browsers. Also I would like to know if this might be the problem... while looking at View>Character Encoding> Unicode (UTF-8) is selected. Also when I use words like: is, or, of I have to hit s,r,f twice to get it to show. Maybe thí clue will help you help me.

This problem is driving me crazy... I have to type everything that I would type into firefox into notepad and the copy it into firefox. I have tried the recommended options and nothing is working... I even found an add-on AVIM which is a Vietnamese input method editor for which I didn't install it a have deleted it. If anybody can help please do

Most recent update... after removing AVIM and firefox crashed just after that it seems that my issue is closed as it has gone away.
