Goodness gracious, I hadn't realised adverts had gotten that bad again. You'd think with the ever-increasing backlash against web site advertisement they'd balk at such behaviour on their web site.
So nowadays I have uBlock Origin, Privacy Badger, the "Tracking Protection" in Firefox enabled by default and I'm seriously considering NoScript, too bad it wasn't available for Firefox Android last time I checked.
The UI is cumbersome for this on Firefox Mobile, but it does work.
