[HANG] Firefox hangs When Visiting HKTV with NoScript on

Post by ReporterX »

(Update: Temporary fix
Whitelist jwpcdn.com before you visit HKTV.
The site needs a better handling of the error when jwpcdn is blocked or out of service.)

1. I opened a new profile with only NoScript installed to test it, so NoScript is the culprit.
If I allow scripts to load globally (more or less essentially disable it), Firefox won't hang. Otherwise it will.

Noscript 2.6.9.10
Go to http://www.hktvmall.com/hktv/en/

Allow:
hktvmall.com
scorecardresearch.com

Untrusted:
google-analytics.com

See if the TV in the "TV Box" section loads. If it warns you about unresponsive script, just stop it. Then refresh the page.
Keep trying. You will end up seeing Firefox hanging (memory keep rising) and you need to force close it. :cry:


(Update: This bug is gone after the TV site update)
2. I have RefControl installed to control what gets sent as the HTTP Referer. I set it to send "the URL that is currently being requested" for all third-party sites, like this:
Image

NoScript is set to allow scripts globally. Other functions like XSS, ABE and HTTP cookies are enabled.
I tried to set every website as "normal" (i.e. let them send original HTTP Referer). The TV still couldn't load.
Without it, it could. Any clues what's wrong? :oops:

Hi ReporterX,

What NoScript version? If later than 2.6.9.6, does this happen also with 2.6.9.6?
(old versions at
https://addons.mozilla.org/addon/noscript/versions
*or*
http://noscript.net/feed?t=a
if this does *not* happen in 2.6.9.6, maybe viewtopic.php?f=7&t=20420 is related?)
(You might want to update your signature to reflect your current Fx/NS versions)

When it fails, do you see anything related in the Browser Console? (Ctrl-Shift-J)
(if you don't know what's related, turn off CSS warnings and post everything else you see)
*Always* check the changelogs BEFORE updating that important software!

Confirmed.


HANG WARNING
(IOW do NOT try on your regular, running Profile.)

> 1. I opened a new profile with only NoScript installed to test it

> 2. I have RefControl installed to control what gets sent as the HTTP Referer.

So is it only 1 or 1 + 2?
Do you have only NoScript installed or NoScript + RefControl?
Not relevant.
NoScript alone, & the steps mentioned, cause the hang.
(You don't really need to mark google-analytics.com as Untrusted as it is not allowed, by default.)


If you start out with Allow Globally the site will load.
I image there are some other sets of domains if Allowed will allow the site to load correctly too [or maybe not], but that's not really the point.

During this "hang", which seems that it will not subside, FF EATS memory (& CPU), so I suppose at some point you will crash. Once initiated, doesn't look like there's much you can do except to kill FF.

@therube: can you reproduce with NS 2.6.9.6?

What NoScript version? If later than 2.6.9.6, does this happen also with 2.6.9.6?
(old versions at

*or*
http://noscript.net/feed?t=a
if this does *not* happen in 2.6.9.6, maybe viewtopic.php?f=7&t=20420 is related?)
(You might want to update your signature to reflect your current Fx/NS versions)

When it fails, do you see anything related in the Browser Console? (Ctrl-Shift-J)
(if you don't know what's related, turn off CSS warnings and post everything else you see)
Updated now. It is Firefox 34.0.5, Noscript 2.6.9.10

So is it only 1 or 1 + 2?
Do you have only NoScript installed or NoScript + RefControl?
Not relevant.
NoScript alone, & the steps mentioned, cause the hang.
(You don't really need to mark google-analytics.com as Untrusted as it is not allowed, by default.)


If you start out with Allow Globally the site will load.
I image there are some other sets of domains if Allowed will allow the site to load correctly too [or maybe not], but that's not really the point.

During this "hang", which seems that it will not subside, FF EATS memory (& CPU), so I suppose at some point you will crash. Once initiated, doesn't look like there's much you can do except to kill FF.
(2) is another issue. You need to allow scripts globally to avoid the hang and do the test.
The TV won't load with the steps mentioned above.

(To note, on Linux this is not reproducible, the TV doesn't work ever, just says please get latest Flash but latest version of Flash on Linux is v 11.2.202.425 which I've already got - so I can't investigate further, sorry, I'll leave this thread alone now)

EDIT Confirmed on OpenBSD amd64 / SeaMonkey 2.26.1 (where I don't have Flash)... SM crashes due to OOM.
Let's see if a scorecardresearch surrogate is enough to fix it.

In fact looks like any site with scorecardresearch allowed does that OOM hang thing for me (reproduced also on deviantart homepage). Investigating...

Nope, that just makes it reproducible without allowing scorecardresearch in NS. :(

(For the curious, here's the surrogate:)

Code: Select all

noscript.surrogate.scrbeacon.replacement : _comscore = _comscore || [];window.COMSCORE = window.COMSCORE || {__noSuchMethod__:function(){}}
noscript.surrogate.scrbeacon.sources : .scorecardresearch.com

Any clues what causes the hang?
And why TV couldn't load with script globally allowed (with RefControl)?

Will poke around in the page's scripts, see what references the things in the surrogate (the script has to get past there to run the part that hangs the browser, so I'll see what errors out and if the surrogate can be tweaked to work-around whatever's past there that's giving trouble)

Have you tried leaving RefControl enabled but to send real referrer for things on only that site?

Well, I conclude that the offending code on the TV site is either in

Code: Select all

http://ott-www.hktvmall.com/assets/js/ott.js
or it's related to this code snippet in the page

Code: Select all

<!-- Begin comScore Tag -->
                <script>
                var _comscore = _comscore || [];
                _comscore.push(
                { c1: "2", c2: "17824804" }

                );
                (function()
                { var s = document.createElement("script"), el = document.getEle
mentsByTagName("script")[0]; s.async = true; s.src = (document.location.protocol
 == "https:" ? "https://sb" : "http://b") + ".scorecardresearch.com/beacon.js";
el.parentNode.insertBefore(s, el); }

                )();
                </script>
                <noscript>
                <img src="http://b.scorecardresearch.com/p?c1=2&c2=178248
04&cv=2.0&cj=1" />
                </noscript>
                <!-- End comScore Tag -->
but not sure which, or how to fix.

I notice that all the scorecardresearch script tags are 'async', could that be related to this issue?

Yup! I set it to send the real referrer when I visit this site. But the TV couldn't be loaded. :cry:

Noscript still crashes Firefox. So sad!

Post by ReporterX »

Tried the latest version 2.6.9.12
Unfortunately it still crashes Firefox when I visit http://www.hktvmall.com/hktv/en/

If you allow hktvmall.com & scorecardresearch.com to let the site to run the TV, Firefox will crash. :oops:
Some clients want to visit this site. I have to ask them to uninstall Noscript because of that.
It is a good script and with good protection. So sad.
Any possible workaround?
Thank you.
