 While doing some last minute tests before the release of the port of the
 Tails ISO image verification extension to Web Extensions we realized that
 it was not working on Debian while it is working on Tails and Windows.

 Investigating this further we think that the background scripts of Web
 Extensions are not run correctly in Tor Browser 7.0.9 on Debian. For
 example, running the dummy extension described in
 https://trac.torproject.org/projects/tor/ticket/21270 leads to a ping in
 the console on both Tor Browser 7.0.8 in Windows and Tor Browser 7.0.6 in
 Tails but not on Tor Browser 7.0.9 in Debian. I'm sorry I'm comparing
 different version of Tor Browser on different OSes so I can't tell if it's
 OS-specific or version-specific... Note that they were all in "low"
 security in the slider.

 Here is the code of the dummy extension I used to do the tests, inspired
 from #21270:

 {{{
 $ cat ping/manifest.json
 {
   "manifest_version": 2,
   "name": "Ping Test",
   "version": "1.0",
   "description": "Tiny extension which pings the console from a background
 script.",
   "background": {
     "scripts": [ "ping.js" ]
   }
 }

 $ cat ping/ping.js
 console.log('ping');
 }}}

 The procedure to test it is:

 1. Start a fresh Tor Browser.
 2. Press Ctrl+Shift+J to open the JavaScript console.
 3. Visit about:debugging and load manifest.json as a temporary add-on.

 The output of the console in each case is:

 Debian: 7.0.9 (based on Mozilla Firefox 52.4.1) (64-bit)
