I have a vertical left hand menu created using ul/li tags. I need this to be accessible via the keyboard only. On Chrome and IE the enter key will expand or collapse the sub menu items. On Firefox it doesn't. How do I fix this issue?

As far as I know, this isn't a standard behavior of lists, you probably have both custom CSS and JavaScript to make it work.

Is there an example of your menu online for testing/experimenting?

Is it the computer, or just Firefox?

Start your Computer in safe mode with networking. Then start Firefox. Try Safe web sites. Is the problem still there?
