When I open a new tab, it always starts with the https prefix and not http. Is this something that can be changed to just load http and allow https to be only picked up when it is on the server for a particular site such as internet banking?

The other issue I have, is that cache doesn't appear to be clearing. There is a site I can't access now. The site was down but is now up again, I can access it in Firefox. I've tried clearing cache / browsing history - but STILL won't load.

Any ideas?
