Let's make ad-blocking the default

Because the choice of an adblocker should be left to the user. Adblock plus and Adblock both make a lot of money by letting some ads unfiltered in the default settings. That kind of behaviour could not be allowed built in in a browser like firefox. Plus they have the risk of website boycotting the browser, in the same way than website today forbid adblock, but way more powerful because it could be done server side.

I'm scared of the day we block ads by default. Sure the internet will briefly be a nicer looking domain.

But then sites will support themselves through alternative means, some better, some worse, than the ads we used to have.

And the ads we will still get, on or off the internet will be less informed of our behaviours, resorting to meta-tactics to grab our attention besides simply being relevant to our interests.

As much as I hate the way ads can be displayed to me, I like it when they're relevant to my interests, I like it when I can peruse a quality site that exists because of ad revenue. And I know that I can seek out the ability to block the more annoying ones.
