ABP for IE, "Only secure content is displayed" notifications

Post by Spiff »

Well over a week ago, I replied in the Adblock Plus for Internet Explorer thread Only secure content is displayed.
I was and am hesitant to post the report as a Bug report, as I was and am not sure if the reported issue is an Adblock Plus for Internet Explorer bug, or might be some sort of an Adblock Plus for Internet Explorer 'feature'.
But as there was no reply from the Adblock Plus for Internet Explorer team in the Adblock Plus for Internet Explorer thread, I will now post in the Bug report forum, although hesitant.

This is the case:

Using IE9 without Adblock Plus 1.1 for Internet Explorer, very sporadicly I get an IE notification message "Only secure content is displayed" on some web pages with mixed http/https content, but on most pages I don't.
And also, using IE9 without Adblock Plus 1.1 for Internet Explorer, when I use the EasyList Standard and Dutch EasyList adblocking list TPLs ('Tracking Protection Lists') and also the EasyPrivacy Tracking Protection List, on most pages I do not get those Internet Explorer "Only secure content is displayed" messages, just the same as without those TPLs. (for TPLs, see: http://www.iegallery.com/en-US/trackingprotectionlists and http://www.iegallery.com/nl-NL/trackingprotectionlists)

But since I installed and activated Adblock Plus 1.1 for Internet Explorer (with EasyList + EasyList Dutch), I get those IE notification messages "Only secure content is displayed" on quite a lot of web pages.
On sites that use some mixed http/https content, I guess.
(see: http://support.microsoft.com/kb/2625928/en)

Two examples of sites that generate that "Only secure content is displayed" message in Internet Explorer with Adblock Plus 1.1 for Internet Explorer enabled:
https://startpage.com/
https://www.security.nl/

Disabling or even removing the EasyList Standard and Dutch EasyList adblocking lists TPLs and also the EasyPrivacy TPL, that doesn't make any difference.
Only setting "Disable everywhere" for Adblock Plus 1.1 for Internet Explorer, or disabling the Adblock Plus 1.1 for Internet Explorer add-on, stops the IE notification message "Only secure content is displayed" appearing on those webpages.

The strange thing is, before installing and enabling Adblock Plus 1.1 for Internet Explorer (with EasyList + EasyList Dutch) (or after disabling it), I did not get that "Only secure content is displayed" message on those sites.
And with using IE9 without Adblock Plus 1.1 for Internet Explorer, and using the EasyList Standard and Dutch EasyList adblocking list TPLs and the EasyPrivacy Tracking Protection List, on most pages I did not get those Internet Explorer "Only secure content is displayed" messages.
So, I wonder what is it that Adblock Plus 1.1 for Internet Explorer does that causes those "Only secure content is displayed" messages on certain pages and that the EasyList Standard and Dutch EasyList adblocking TPLs do not do?

Does anyone know?
Is it an Adblock Plus for IE feature?
Is it an Adblock Plus for IE bug?
Will it be corrected in a next build?
Is there a way to modify the mentioned behavior, other than disabling Adblock Plus for Internet Explorer, and other than to change the setting in Internet Options to enable the display of mixed content? (Which is not recommended as that is an 'unsafe' setting, "this setting may make your computer vulnerable to viral, fraudulent or malicious attacks".)

System details:
Windows Vista Ultimate 32 bit (version 6.0.6002 SP2 Build 6002)
Internet Explorer 9 32 bit (version 9.0.8112.16421)
Adblock Plus for Internet Explorer (version 1.1.0.0)
Add-ons in IE: Adobe Flash Player, Adblock Plus 1.1 for Internet Explorer, PDF-XChange Viewer IE-plugin, Microsoft Silverlight, VTExplorer, WOT, and a bunch of default Microsoft add-ons for IE.
Search engines in IE: Startpage http, DuckDuckGo, Google.
Tracking Protection Lists in IE: EasyPrivacy, EasyList Standard, EasyList DutchAdblockList.
(N.B. As mentioned, disabling and even removing the EasyList Standard and Dutch EasyList adblocking lists TPLs and also the EasyPrivacy TPL, that doesn't make any difference.)

No - that is NOT a fix.
By enabling "Display mixed content" in Internet Explorer, you lower the security settings.
See:
https://support.microsoft.com/kb/2625928/en:
"Internet Explorer blocks non-secure content to keep your information safe and is set to Prompt by default. When this setting is set to Enable, Internet Explorer does not prompt you with the "Only secure content is displayed" message even if the webpage is using non-secure elements."
So:
If you don't want to lower your Internet Explorer security settings, do not enable "Display mixed content".


By the way,
I am still waiting for a response by the Adblock Plus for Internet Explorer team regarding this issue.
