Firefox 23 will block non-SSL content on SSL pages by default
In other words, start using the `//url.to/something-here/` shortcut and the world will be a better place.EDIT: Use `//` instead of `http://` or `https://` and it will use whatever the protocol of the page being fetched is using.EDIT 2: Double check when you use the `//` shortcut that the website you are linking to supports HTTPS, some still don't and they don't redirect properly...
