SETUP: Firefox 57/58 Windows 10 DESCRIPTION: When opening the Ryanair website I search for a flight on a certain date. The result is that no prices are calculated or shown on Firefox so that the booking process cannot be completed. This behaviour does not occur on my machine when using Chrome or Edge. Also the same Firefox version on an Ubuntu installation does not show this behaviour. Tracking protection is set to "Only in private" and cookies are always accepted until they expire. https://www.ryanair.com/de/de/booking/home (Search for any flight) 1st screenshot shows my Firefox whereas 2nd screenshot shows Chrome.
