It’s not Facebook, it’s you. You’ve got malware.
The malware is called Page Rage and Drop Down Deals. Head to this page to disable Page Rage, and this page to uncheck everything related to Drop Down Deals. And if you’re not infected, then no, I don’t suggest visiting either of those pages. Only go there if you’re having the issue.
Once you’ve visited those two sites with every web browser on your system, then scan the living daylights out of your computer with your antivirus/antimalware software. And install Bit Defender Safego to reduce the chances of something like this happening again.
And if you hear anyone talking about how great Page Rage or Drop Down Deals are… Well, ignore them. It’s just adware, 2011 edition.
