My first post, and I apologize if I'm not doing so correctly.
I've noticed an issue with some Adsense ads on Firefox - possibly only with the responsive ad type (though I haven't isolated that yet). Seems to have started during one of the last two Firefox updates.
Ads and page seem to be completely loaded, but the "loading page" indicator in the Firefox tab keeps spinning, and checking the list on the Back arrow shows repeated listings of the current page, as if it is refreshing over and over. This continues as long as the page is open. Analytics shows no change in page views, and Adsense reports don't look out of the ordinary.
I've made no recent changes to page or ad code. Does anyone have any insight? Thanks.
