If you have NoScript or other script blocker, it will prevent the popup.
I didn't confirm (no popup) but I'm already in "processing" status. Is this because I only ordered recently (after the price increase) and so I don't actually need to re-confirm anything?
same situation here, tried on multiple browsers many times and no pop-ups but says processing but also ordered recently. confirmation on whether or not this is the case by Josh would be nice before a fill bfl's inbox with confirmation requests
