Since today I all of a sudden get the yellow “Insecure content” warning message on sites like facebook and spiegel.de.

Link to “more information” goes here: Comodo Dragon - Block Insecure Content,Best Browser | Comodo Dragon Browser

I do not use the Comodo DNS option, my router is set to use Google DNS.

Do others see this also, is this a bug?

Comodo 17.1 on Win7-64

Issue was a bug in Adblock Plus experimental trying to address a Chromium bug (49001 - chromium - An open-source project to help move the web forward. - Monorail).

A new update of Adblock fixes the insecure content message.
