Chrome Self-Signed SSL HSTS
Ignoring unsecure-site blocking on Chrome with self-signed SSL and HSTS
When viewing a development site that is using a self-signed certificate, it's normally possible to ignore the security message by "continuing" onto the site.
However, sometimes (and I don't know why) sites will give the message but not the ability to continue.
It turns out that Chrome has an easter egg that allow you to quickly and easily ignore the message.
Simply type thisisunsafe
into the page (it will not appear on screen while typing) and hey-presto.
