Looks like it wasn't just FR who have been changing their booking engine recently!
I've been looking at flights on LS today and their website used to, quite rightly, show the full fare on the flight select page.
They've now gone back to quoting only the base fare not including taxes.
When you do select a fare this 'FR-copy' box appears in the top right of the page quoting the fare and the taxes and shows the total fare.
