Looks like just a bug to me.  Please file in the Core product?

Mounir, shouldn't IsDisabled() on nsGenericHTMLElement just return false?

Attached patch Patch v1 (obsolete) — Splinter Review
Indeed, with bug 557087, I did introduce |IsDisabled()| but it seems that this bug didn't cause the regression:

So I guess the described issue must be quit old.

Here is a patch that might fix it. I will write some tests as soon as I will have a try run done.

I think this pass should pass our test suite.
It's lovely to see that we had tests checking that <div tabindex=1 disabled> was actually not focusable... :)

Antaryami, thank you for reporting that issue. That was a very valuable feedback!
That bug should be fixed in Firefox 13. The fix will be available soon in our Nightly builds.
