Given the historical record on attempts at Mercosur-EU trade deals, this is likely to fail yet again, since the EU’s agricultural voting bloc (mostly in France and Italy) doesn’t really want the market to be populated by cheaper products from abroad (at least not any more than it already is). But at this point, given the several ongoing food crises that Russia’s invasion of Ukraine caused, the chances for a successful agreement are about as high as they can go, so they might as well go for it.

I really don’t see how supporting Manifest V3 is a problem. It’s still going to be used by many extension developers, and there’s no harm in its availability as long as you can still block WebRequest, which is currently the case. On the Mozilla taking Google’s money point, sure, that’s true, but it doesn’t seem to have affected too much of the browser, other than search defaults abd a few other things that can be very easily turned off or removed entirely. I wouldn’t say the chances are particularly high for Manifest V2 to be completely removed, personally.

(Do note I’m not an astrophysicist, so this may be a bit wrong, but I think the main part of it is right.) Not exactly. Everything in the universe is constantly drifting away from everything else. The reason it is pretty much only visible at the scale of galactic clusters is that literally every force in the universe overpowers this expansion, unless the distances between the objects are truly absurd, in the range of millions or billions of light years.
