 rustybird reported that NoScript is broken when setting
 `TOR_SKIP_LAUNCH=1` (see comment:13:ticket:26128):
 """
 This seems to break on a fresh 8.0a9-build3 linux64 installation whenever
 `TOR_SKIP_LAUNCH=1` is set (with system `tor`
 running on the usual ports). JavaScript is effectively disabled and the
 browser console says:

 {{{
 [06-25 18:36:50] Torbutton NOTE: security-prefs.js initialization complete
 Error: Could not establish connection. Receiving end does not exist.
 ExtensionCommon.jsm:456:12
 }}}

 Some sort of extension startup race?
