If you don’t keep up with updates for your web browser, it’s time to rectify that if you want to make a ferry reservation. Here’s the notice from WSF:
Please be advised that as of November 1, WSF’s reservations website will no longer be compatible with older versions of some browsers, including Microsoft Internet Explorer version 10 or lower; Safari version 6 or lower; or old versions of Chrome and Firefox on PCs with automatic updates disabled. This is because the older version of these browsers do not properly support the secure HTTPS communication protocols required to make our website compliant with Payment Card Industry security standards. Please make sure your browser is updated to the latest version.
