FireFox? That feels right.
I deleted an extension I had no recollection of installing, and . . . so far, the issues have not reoccurred. My own simulation red writing made me jump, but no real pressure to buy T shirts with pictures and writing on them. Why, oh why, do people like writing on their shirts? Come to that, why do they like pictures on their skin? But that's another issue.
Thank you Mr box. Waiting with baited breath. Oh, and no, I can't for the life of me remember what I zapped.
