Can't capture full page Waardering 1 van 5 sterren

I've used this plugin before with earlier versions of Firefox, but with version 18 it can't capture the full page anymore. I tried capturing the settings page for a calendar on Google Calendar. I only got what was visible on the screen.

Deze beoordeling betreft een eerdere versie van de add-on (2.3.8.1-signed).
