A "no-popups: * true" rule will block new tabs opened from "chrome://extensions/"

[gorhill]

Describe the issue

As first reported at http://www.wilderssecurity.com/threads/ublock-a-lean-and-fast-blocker.365273/page-77#post-2578260:

When i turn the logger on and click the Get more extensions -link, I will get this and only this:

13:20:37 no-popups: * true -- popup https://chrome.google.com/webstore/category/extensions?hl=en-US

One or more specific URLs where the issue occurs

chrome://extensions/

Steps for anyone to reproduce the issue

1. Have chrome-scheme in Whitelist.
2. Have no-popups: * true in My rules.
3. Paste chrome://extensions/ in the address bar of a new tab.
4. Scroll to the bottom, click the link "Get more extensions".
5. Result: the new tab is automatically closed.

The new tab should not be affected by the no-popups: * true rule, as the new tab was opened from clicking a link in a whitelisted page.

uBO can't inject its content scripts into chrome:// (and likes) pages, so it is unable to detect that the new tab is legitimately opened by the user. Furthermore, uBO disregarded the whitelist status of URLs with non-http/non-https scheme.
