Firefox 1.5: Cursor, Home and End Keys don't work in options

This could be somehow related to CORE-2184.

You can't use Shift+End to highlight the default homepage (Tools->Options), Home or End don't even work by themselves (without key Shift pressed). If you press left or right cursor key the cursor won't move. Notice also as stated in CORE-2184 that the cursor doesn't blink while in options, and if you keep pressing keys you'll make it blink. Notice also that those keys work if you move the mouse while typing.
