I encountered an issue with my home page. I could click on the link to my email or to one of the news links and they would not open unless I right clicked and opened them in a new tab. They had always worked previously. I use Comodo Dragon as my primary browser and my home page is ATT.net. I tried everything, clearing the cache and cookies, checking all my settings, and I even uninstalled Comodo and re-installed. Then I clicked on the PrivDog icon and that was when I realized that the only thing that had changed on my browser was the addition of PrivDog.
I disabled it as an extension and my page is now back to normal. Hope this helps someone that may be having the same issues.
