This. I’m pretty sure this is a result of the ad engine changes they made to chrome a few months ago. Manifest V2 is what enables uBlock Origin to be so effective iirc and they’re removing it in chrome in favor of Manifest V3.
No, Google pays Firefox to make it seem like it still has competitors and isn't a monopoly. However, a key condition of that payment is that the default search engine in Firefox is Google. They change that, they lose most of their funding -- not most of their Google funding, most of their revenue (which is nearly all Google).
Wouldn’t Mozilla be motivated to fuck google as hard as possible?
If they still existed as an actual company, sure. But, it's not. It's a corpse that Google animates with their huge funding to make it seem like they still have competitors. Technically, Google doesn't own Mozilla, but in a 2012 report, 85% of their funding came from Google. So, they're never going to do anything that risks that funding.
Back in 2005, they started paying Mozilla to promote the Google search engine via their browser. Chrome still wasn't a thing back then. The weird thing is that they never stopped those payments even today, they even increased them on almost a yearly basis.
That was back then.. Why would they do it now that it no longer makes financial sense since Mozilla is just 3% of the browser market? No clue
