1231273 - Unblock Tracking Elements does not work

Status: NEW

(SeaMonkey :: Security, defect)

Description

[Rainer Bielefeld]

This one is a follow up to "Bug 1223785 - Tracking protection blocks images from https://fotki.yandex.ru/" 

Steps how to reproduce with  SeaMonkey German 2.39 final Mozilla/5.0 (Windows NT 6.1; WOW64; rv:42.0 from official download area)  Gecko/20100101  Firefox/42.0  Build 20151103191810  (Classic Theme) on German WIN7 64bit:

1. Menu 'Edit → Preferences → checkmark to all 5 Tracking and Safe Browsing
   options
2. Quit → Relaunch Seamonkey
3. In Browser open
   <http://www.youpickit.de/Produkt/Connor-Klebestift-6/2257386>
   » Above page contents bar with tracking warning and 3 buttons appears
4. Click [Unblock]
   » As expected bar appears
   » Unexpectedly bar reappears after few secons

Additional info:
a) As per  Bug 1223785 comment #1 Step 3 Blocked pictures will be 
   missing in page. [Unblock] should make pictures appear, but 
   at least in that case background picture will not appear

b) This is not a general problem for all webistes, for example [Unblock] works
   fine on  <https://fotki.yandex.ru/next/users/worldpressphoto/album/495971/view/1137029?page=4> and others.
   (Try with a new user profile).
   But on lots of pages I see this endless useless unblock loop
c) I only found the obvious blocked picture in step 3. I did not yet test
   what contents was blocked on other pages.

d) For URL from (b) [Unblock] still worked fine with en-US SeaMonkey 2.33.1 
   Gecko/20100101 Build 20150321194901 (Classic Theme) on German WIN7 64bit:
   Unblock button disappears after first click on it.
   So this behavior seems to be a regression

e) Still worked fine with
e1)en-US  SeaMonkey 2.38  (Windows NT 6.1; WOW64; rv:41.0)  
  Gecko/20100101 Firefox/41.0 Build 20150923195647  (Classic Theme) 
  on German WIN7 64bit

Is this bug report still current?

I confirm that the bug described happens in Seamonkey 2.39.

User agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:42.0) Gecko/20100101 Firefox/42.0 SeaMonkey/2.39

The bar offering to unblock goes away after clicking on unblock, then comes back a few seconds later.

In the second page the unblock bar went away after clicking unblock.

However, when I tried using Seamonkey 2.44a1 the unblock bar never appeared for either link.

User agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:47.0) Gecko/20100101 Firefox/47.0 SeaMonkey/2.44a1

Has something changed? All five of the checkboxes are checked and I have never visited these pages before.

Indeed, this one needs some new research. 
For me still REPRODUCIBLE with unofficial (from <http://seamonkey.callek.net/contrib/>)  en-US SeaMonkey 2.44a1  Mozilla/5.0 (Windows NT 6.1; x64; rv:47.0)  Gecko/20100101 Firefox/47.0 Build 20160208090255  (Default Classic Theme)  on German WIN7 64bit if I use my default User Profile.
But  with a fresh new user profile no warning bar at all.  I will do some more tests, soon.

Still REPRODUCIBLE with  en-US SeaMonkey 2.40 final Mozilla/5.0 (Windows NT 6.1; WOW64; rv:43.0)from official download page,  Gecko/20100101  Firefox/ 43.0  Build 20160120202951, (Classic Theme) on German WIN7 64bit and my normal profile and steps due to original report (although contents does no longer exist): All blocking related buttons in bar below TABs remain. Results different on <https://unofficialseamonkeynews.wordpress.com/>: only "preferences" button in tracking related bar will remain after click on [Unblock]

But not reproducible at all in safe mode.
It seems I simply made a mistake and associated the different (better) behavior of 2.33 to the other SeaMonkey Version number, but may be the different behavior was caused by an add-on what is active in 2.39/2.40, but not in 2.33?
More careful research required!

Different observations at wordpress-URL nothing new, same already in Comment 1.

Comment 10

[Frank-Rainer Grahl (:frg)]

Tracking protection is broken in 2.39+ as stated in bug 1260457. Please test with recent 2.44a2 or add the preferences from the file pref.js.appends.txt to your prefs.js and see if it works again afterwards.
