Tab selects don't work in Firefox...

[the-t-in-rtf]

In looking at the demo site, I discovered that the tab navigation doesn't work in Firefox 30 or Firefox 31. Tabbing selects:

1. The code block under "Link to the JS file"
2. The code block under "Add the CSS file (or append contents to your own stylesheet)"
3. The code block under "To specify settings after the init, use this syntax"
4. The code block under "You can instantiate the selectBox also through a classic OOP way"
5. The browser location bar

At no point can you navigate to the select demos using the tab key.

If you mouse click on an element, the arrow keys work, seems like just the tab navigation is broken.

Seeing the same issue although it only looks like this is FF on a mac

Confirmed, I was testing with Firefox on OS X.
