I hate that web developers only develop for IE. It shits me on so many levels. My mum has been having issues for ages trying to get to the Westpac Altitude points website. At one stage, it would refuse to even let her try and log in because it would only allow IE, based on the browser’s useragent string. It seems that changing the useragent isn’t neccessary on this site any more, but now when logging in, firefox pops up with the following error:
Firefox and images.pinpoint.net.au cannot communicate securely because they have
no common encryption algorithms
when firefox tries to download the images for the site.
To solve this problem, to go the about:config page in firefox, and set the option:
security.ssl3.rsa_rc2_40_md5 and set to true.
For other websites (e.g. Amazon) that I have seen have problems may require different security options to be set. I worked my way down the list of security options and changed the ones which were false to true, one by one. Maybe this might help somebody else one day.
