Testing Flash Block, Week 2:

** Using a fresh profile with Firefox 53 Release ( https://archive.mozilla.org/pub/firefox/releases/53.0/ )
(This can be tested on Nightly too, but 53 Release is preferred)

1 - set the pref "devtools.chrome.enabled" to true

2 - open Web Developer -> Browser Console

3 - Paste the following all together and press Enter.
(Note: This will put Flash in Ask-to-Activate Mode)


Preferences.set("plugins.flashBlock.enabled",true);
Preferences.set("plugin.state.flash", 1);
Preferences.set("plugins.favorfallback.mode", "follow-ctp");
Preferences.set("plugins.favorfallback.rules", "video");
Preferences.set("plugins.navigator.hidden_ctp_plugin", "");


4 - Sanity check:

- Go to translate.google.com and make sure that the infobar to activate Flash is displayed
- check that you're in Week 0 or Week 1 of the list (* instructions at the end)


5 - Open browser console again to paste and Enter:

Preferences.set("browser.safebrowsing.provider.mozilla.updateURL",Preferences.get("browser.safebrowsing.provider.mozilla.updateURL").replace("shavar.services.mozilla.com/", "shavar.stage.mozaws.net/"));
Preferences.set("browser.safebrowsing.provider.mozilla.nextupdatetime","1");


7 - Restart the browser


8 - Wait a while. You can keep an eye on the pref "browser.safebrowsing.provider.mozilla.nextupdatetime" in about:config.
Once it changes to a big value again, you're good to continue


9 - Sanity check:

- Check that you're now in Week 2 by running the checking instructions again
- go to translate.google.com and now make sure that the infobar to activate Flash is NOT displayed


10 - If everything worked correctly until now, it's all set.
You can start testing the websites requested to make sure they don't break with this new configuration.


==========  Checking what's the corresponding Week for the blocklist =========

Paste all of the above lines all together in the Browser Console, and press Enter:

function checkWeek() {
  let classifier = Cc['@mozilla.org/url-classifier/dbservice;1']
                     .getService(Ci.nsIURIClassifier);

  let { NetUtil } = Cu.import("resource://gre/modules/NetUtil.jsm", {});
  let table = Services.prefs.getCharPref("urlclassifier.flashSubDocTable");
  
  for (let i = 1;;i++) {
    let url = `https://week${i}.flashstudy.example.com`;
    let uri = NetUtil.newURI(url);
    let result = classifier.classifyLocal(uri, table);
    if (result == "") {
      console.log(`You're in Week ${i-1} of the Flash Shield Study`);
      break;
    }
  }
}
checkWeek();
