Hi robertbrown. If the inputs are wrong even outside Firefox, the issue may be with the operational system. Seems to me that the layout of your keyboard is wrong. You can see if the "Start Bar" (The one in the bottom) contains the "Language Bar". This is described here: http://windows.microsoft.com/en-US/windows-vista/Change-your-keyboard-layout If you can't find this square on the bar, you can do this on the Control Panel: http://www.conversationexchange.com/resources/keyboard-language.php If this answer solved your doubt, please mark it as the solution.

for Foxtab see solution from '''Wolfcity''' : http://forums.mozillazine.org/viewtopic.php?p=11754893#p11754893 thank you
