#24263: Tor Browser 7.0.9 on Debian doesn't run background scripts from Web

------------------------------------------+----------------------
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)
