Internet Explorer 8 is great fast, secure and convenient. but there a couple of annoying things that almost made me go back to Firefox. but instead of avoiding the problems, I took the time to fix them. here is one of them:

Security Warning for secure pages:

this pop-up is annoying, every time I wanted to check my Google reader feeds, or any other secure page I got this warning pisses me off. so how do you disable the message?
easy! do this:
On Internet Explorer click on Tools then click on Internet Options when the Internet Options property comes up, click on the Security tab:

Select the Internet zone and click on the Custom Level button. the security settings will come up:

scroll down to Miscellaneous and Enable Display mixed content then click on Ok. restart IE. that should stop the security warning display.
