I'm a bit conflicted. Firefox was open to it's default home page and after a few minutes of inactivity a new tab opens by itself to this (seemingly harmless) webpage: http://barisderin.com/?p=2264
The title on this page is "Facebook Message Seen Disabled" which I thought was a legitimate add on that I have installed: https://addons.mozilla.org/en-US/firefox/addon/facebook-message-seen-disable/
I'm not sure how to proceed. I do use the add on but I don't want to have random pop ups and now I don't think I can trust them. I also have adblock plus installed, and I ran adaware and the only thing found were the registry keys
EDIT: how on Earth do we not have a adware tag?
