I trust they'd only show things aligned with their brand and not shill Nestle coffee.

Is the Fifa World Cup really that relevant and aligned with Mozilla and Firefox?

To compare the world cup to McDonald as or nestle coffee is crazy. The world cup is the largest sports event in the world and is followed all across the globe, its expected to have 5-6billion people following it in some way and 1.5 billion watching

Both McDonalds and Nestle are huge megacorps with extensive influence globally.

What if Samsung, Xiaomi, or Apple was promoted in Firefox? They all have very significant market share in smartphones globally, and Apple trades places with Nvidia for the title of most valuable company in the world, but I'm sure most people wouldn't want ads for them.

Or maybe if Toyota or Volkswagen did a promotion: they have both sold billions of cars worldwide under many different brands, so I believe they are a closer comparison with the World Cup in terms of just numbers. But even still, most people aren't car nerds, and will dislike the promotion of either company's latest model.

Or maybe if Saudi Aramco was promoted instead, the largest oil company in the world producing millions of barrels per day, and being very significant for the energy needs of most countries. Nearly everyone would be unhappy for this kind of promotion.

But what if you believe that companies don't count, because "Mozilla is too perfect to suck up to them", here are some more examples that are specifically events, like the World Cup:

• Taylor Swift concerts (or another similarly huge music artist)
• Disney movie showings (or another large media company, like Warner Brothers)
• Eurovision (very huge in many European countries)
• Olympics (or some other large sporting event)
• etc.

I'm sure you wouldn't like many of those, even if they do have similarly large audiences as the Fifa world cup.

The world cup is followed by a significant % of the world so an un-intrusive option asking users if they want to opt in is more useful than it is annoying.

But most people aren't so invested that they want the browser widgets. It would be better if it was an extension that you could install, rather than something baked into the browser (that would be properly opt-in).

It would be beneficial to everyone if it was a separate extension. It would mean less preinstalled bits while probably also giving the people who want the features more of it (since it doesn't have the restriction of being preinstalled into the browser).
