Links not opening in default browser

[cyan3]

I have Google Chrome as my default browser, however if I open a link within the Graal client the page will open in Firefox which was the default browser on installation of my operating system. As far as I can tell Graal seems to be the only application using Firefox instead of the default browser but I'm still not sure if it's a problem with my operating system or the Graal client. This is beginning to bug me because I'm continually copy and pasting the link into Chrome.
