Proxy test failure language is confusing
When Torbutton fails a proxy test, it sets the about:config preference extensions.torbutton.test_failed. It then pops up a dialog warning the user that the most recent test has failed whenever they try to toggle, but it is not clear how the user should go about rerunning the test. We should at least tell them where it is in this dialog.
