When on the web page of any website, random words will be highlighted with a green arrow symbol next to it. I have never had this problem until today and haven't downloading anything recently. The image I attached has the words diapers highlighted with the arrow next to it for an example. I have checked addons and there is nothing unusual or out of the ordinary in my addons. Occasionally, I will also get a little side-bar pop-up thing that comes up on the side of the screen or if I click on anything another tab will open to a completely different website with some sort of add. I have all pop-ups disabled (with few exceptions) so I'm not even sure how I'm getting pop-ups in the first place as Firefox used to be very good with this.
