Whenever I book flights, I always use Internet Explorer, much as I hate doing so. Airlines tend to optimize their sites to work with the operating system's default browser which in your particular case is Safari.

It's better to be safe than sorry when booking flights where you're using a credit card for transmitting payment because financial institutions like airlines, will always update their sites to work with the 'default browser' so to speak, but may not devote resources to other browsers, especially when Mozilla is releasing a new version every couple of months now.

That's just my personal opinion of course, but I've had too many things go pear-shaped using Firefox to book flights in the past that I won't take the risk anymore.

Thanks Xircal, much appreciated.

I have come to the same conclusion as my Bank told me similar with regard to the problem of not being able to log off.

Have a good day and thanks again.

Best wishes.
