Hello: I use Mac OS X 10.6.8 with Firefox 34.0. Just a couple of days ago, at https://www.youtube.com, I started getting the pop-up warning titled "This Connection is Untrusted" with the message "You have asked Firefox to connect securely to ad.doubleclick.net, but we can't confirm that your connection is secure. ......." The whole message is in the attached screenshot image.

Googled the web for a solution, but did not come up with one.

Could you let me know how to get rid of this?

Thank you! R.
