@freakazoid you "scrape" the screen off to get at the underlying data. Consider the scraping lawsuits that come from Ryanair & Southwest airlines. The whole point in scraping those sites is for consolidators to present the flights side-by-side with competing airfare. The graphics are discarded, the data is harvested.
@freakazoid anyway, I'm trying to understand your original statement. You seem to be saying an FF plugin can grab the CF site, but something is missing here b/c the site inherently mistreats #Tor users. How does that work?
