nothing new here. esr from trixie; release and devedition from packages.mozilla.org. just updated and ran all three to see. sponsored and recommended crud was off (it is literally the first things that get changed on new installs) and are still off.

edit to add: on my android 'tablet' (phone without a sim), which i couldn't check last night.. updated browsers, then: fennec had this world cup ad in it. firefox nightly did not. still trying to get firefox release updated to see (it's only on 148).
