I am still unsure whether I am happy about it yet. I hate a window that comes up wanting me to click yes or no when page has secure and unsecure data on it
I haven't tried these myself....
Option 1Tools > Internet Options >Security tab
Select "Trusted Sites" with a right check mark icon. Click on sites button and add frequently visited website names that you trust.
Option 2 (but not necessarily recommended since it's shutting off a security notification)
Tools, Internet Options, Advanced
Near the bottom, uncheck (Try the first one, second is optional):
> Warn if changing between secure and non-secure mode
> Warn about invalid site certificates
