Did you skim and miss how they plan on blocking intrusive ads and cross-domain tracking/retargeting by default, and improving the existing tracking protection functionality? There are certainly more mentions of privacy than you cite.

Guilty, thank you :). I was hoping to see it higher.

They already have containers: https://addons.mozilla.org/en-US/firefox/addon/multi-account...

Though I would prefer if it were a bit harder to accidentally leave a container when opening a new tab.
