Inquiry in Firefox are added in a page context menu. But it don't saves a page from Firefox really. It sends a page url to Inquiry and Inquiry loads this in invisible IE windows and then saves the page from IE.
It's very bad way, but we cannot convert Chrome addon to Firefox addon and we don't have time to create new Firefox addon now. Therefore it's a bad idea to save pages from Firefox:(
