Tails

First access with NoScript allowing boum.org: mirror with name in .de.
Second access in private mode, no boum.org in whitelist, name in tux33.fr
FF 51 (debian experimental), new profile, no preacceptance of boum.org: url in 24.dl.amnesia.boum.org
(I guess the extension keeps a cache and it bypass the private mode)
new empty profile with ff 0.51b from debian experimental: works only if adblock is disabled (allowing tails.boum.org is not enough)

This does not work on 51.0~b1-1. The download will fail when trying to resume

New try after reboot to make sure no old version of a library was used, same pb, different exception (actually now it’s the one in the mozilla bugreport). Note that download is not failed now, but is still marked as “going”, just stalled. Works again when removing the hosts entry and pause/start again.

That’s due to a bug in Firefox. (https://bugzilla.mozilla.org/show_bug.cgi?id=1275289)
According to https://hg.mozilla.org/mozilla-central/rev/0fc7e282d053 it should be fixed in 51.0a1, but I did not verify that commit is in there.

Yes there is caching of the mirror URL in the extension.

That means: we need to modify the manual test instructions saying that AdBlock cannot be enabled, correct?

Similar for me (just different mirror).

Same here.

Apart from that, after deactivating JS with NoScript on the website, the download crashes directly after starting (no matter which URL is being used).

And I can also confirm with FF45.6esr:

NS_ERROR_NOT_AVAILABLE: Component returned failure code: 0x80040111 (NS_ERROR_NOT_AVAILABLE) [nsIHttpChannel.responseStatus]  downloader.js%20line%2050%20%3E%20eval:139

FWIW I’ve received reports that uBlock breaks DAVE. Didn’t triage/forward them yet.

Please report this as a separate bug. Thanks!

> FWIW I’ve received reports that uBlock breaks DAVE.

I’m told this can be reproduced:

• even with all uBlock filters disabled
• even toggling the 4 features of uBlock “for this site”

I’ve received this stack trace:

console.error: tails-download-and-verify:

This part of our lib/downloader.js is monkey patching the Firefox download manager. I’m not sure if this code is still needed nowadays, so perhaps the best option would simply be to drop it (if that’s enough to fix the bug). Maybe uBlock Origin is doing something similar in a way that conflicts?

Next step: document simple steps to reproduce and ask Giorgio what’s going on, and if we can drop the monkeypatching.

#11 Updated by anonym 2017-01-24 12:16:58

During the Tails 2.10 manual test sessuin:

• I noticed that “The URL should only start with dl.amnesia.boum.org if Javascript is disabled in your browser” only seem to work reliably if the browser is restarted, so I added that to the test instructions (commit:142dea45)

• I also added two questions/requests for clarifications (see `XXX`:es) to the test instructions for “Test a disabled mirror”. I think I got how to do this test the first time (when I merged it) but now I don’t remember how I did it, and cannot make sense out of it. Or maybe I did it wrong that first time as well. :S

I think this specific test is invalid, and I don’t understand how it can possibly have ever worked: the page that’s being used for this test (https://tails.boum.org/install/debian/usb/) is DAVE-enabled. It doesn’t display any link to the ISO, and DAVE runs its own JS in order to pick a mirror for the download itself, so that should work regardless of the browser’s JavaScript settings. I’ve thus removed the bits that seemed wrong to me (commit:86c3b4da40e4e11c1829767802c37547bbf28de7). Sorry if I misunderstood something!

I guess the intention behind this test was to validate the JavaScript code we use on other parts of our website to pick a mirror; such code is run just like any other web active content, and not by an add-on, so it is affected by the browser’s JS settings. Such a test could be valuable. This could be tested on another, non-DAVE-enabled download page, such as https://tails.boum.org/install/download/openpgp/; but then it’s not testing DAVE, so if we reintroduce this part of the test, then it should be moved to another section.
