I did! I had recently downloaded two programs so I could gif things and one of them downloaded extra crap that I didn’t want… which caused the pop ups and ads all over my tumblr dash as well as my facebook. I just had to restore my computer back to the last update it had and reinstall those two programs making sure I unchecked all the boxes asking if I wanted to download anything else.
Totally frustrating, but I’m ad free now!
Are you having this problem too?
