"Scenario Outline: The default XDG directories are usable in Tor Browser" is fragile
Quite often, we see "I can save the current page as "index.html" to the Downloads GNOME bookmark" fail after "I start the Tor Browser in offline mode" succeeded. When this happens, the screenshot shows the "Proxy server is refusing connections" error in Tor Browser.
Could it be a race condition, where we can't save the error page while Tor Browser is still trying, or something?
