Can you reproduce with Firebug disabled?

I'm in an odd position here.
* On my desktop: right-clicking said elements doesn't open a context menu. (Firebug is not installed here). It doesn't throw above exceptions.

* On my laptop, at the moment, a context menu is opened. (Firebug installed).

I can't reproduce this with Firebug disabled.

It looks like Firebug is adding the ability to open context menus for these elements.

I think you should be able to (1.right-click 2.inspect) these elements however, should we morph this bug to reflect the actual problem?

This should have been fixed a long while ago.

This should have been fixed here: bug 708643

Johan, can you still reproduce this? (works for me)

Please re-open if you still run into this bug.

No, the bug has not been fixed, the exceptions are still thrown with with Firebug.

I filed this bug to deal with the bug where the context menu is not shown for form buttons and select elements (With Firebug not installed). I suppose I forgot to add the bit about the context menu not showing up under 'Actual Results' in the STR, doh!

However, the bug is being dealt with in bug 433168, I'm waiting for a review.

So I suppose this bug can remain closed.

Cheers Paul!
