Blocked test is not very informative [if blocking is in place]

[Thorin-Oakenpants]

Catch 22. The test returns a blank page - as per https://github.com/ghacksuserjs/ghacks-user.js/issues/263

Suggestion(s):

💡 make the blocking landing page NOT blocked ( blocked.html ) and explain it (as per existing) but provide a TEST link to a secondary page ( eg blocked-test.html )

That's a good idea. Instead of a link, we could also iframe the blocked page and on the top-level page say something to the effect that the iframe should be empty.

• Possibly provide a landing page for all five tests with 5 iframes plus links to load all five pages in a new tab eg https://itisatrap.org/firefox/its-a-test.html
