Can't Send Invoice - Flashing Screen (Firebox)

[igotgames1134]

This just started, I believe, yesterday.

When I go to send an invoice on Firefox, I get a constantly flashing screen and unable to send the invoice.

I have to open up IE just to send an invoice. 

I'm on Win X and have the most recent Firefox - anyone else running into this issue?

And that of course should have said Firefox in the title but I don't know how to edit it now...
