      I don’t just mind that Google does user-unfriendly crap with their monopoly browser. What I really hate is the Orwellian doublespeak about how this is really all to make things better for their users.

      The alternative is that any extension can steal all your cookies and manipulate any content on every page you visit. Unfortunately that's how any API with the capability of the webRequest API must work, because that's how manipulating the HTTP stack works.

      That's why we are planning to remove APIs that cannot be site/origin bound, and providing the user with controls to pick what extensions they want to run on a given site. Because that's a necessary step in addressing malicious and abusive extensions.

      Why not just curate extensions better? Or trust users with the risk of malicious extensions rather than forcing them into a ridiculous per-site authorization they may not want?

      Reviewing a non-trivial extension takes a professional vulnerability researcher like me 2-3 days, it is way beyond the current state of the art of program analysis to automate. Curation can help eliminate trivial junk, but is not a good solution.

          There are what, a dozen ad-blocker extensions that represent 97% of blocker usage? Maybe 5? But presumably nobody can afford to review these and grant exceptions?

          I can see the headline now: "Google Bans Competition in Adblock Market". Restricting users to the 5 biggest/established players has its own problems.

          I think it's not a good idea to castrate APIs just because some users install malicious extensions. I hated this excuse when FF used it to drop XUL. Whole Chrome store and Play store are minefields with data stealing apps, but limiting the API definitely won't help that.
