Why does a ChromeWorker throw "Components is not defined"

Question

The documentation on ChromeWorkers says that they have "chrome privileges", and chrome privileges are supposed to mean they can do anything, but when I create a ChromeWorker and try to use Components I get an error that 'Components' is not defined..

So my question is 1) why is Components not available? 2) what is available to a ChromeWorker?

Answer 1

You cannot access the Components object because the Components object isn't threadsafe. A ChromeWorker gives you access to everything a Worker has access to, and c-types.
