Since the first version, ABP stops working if you have the IDM (INTERNET DOWNLOAD MANAGER) addon enabled. Doesn't block anything: flash ads, popups, any kind of ads... I reported this problem since the first version, but nothing got solved. I use IE 11 with the latest updates.

I will try with dev build 1.3.763 right away. But with latest 1.4 still doesn't work.

if 1.4 doesn't work don't try 1.3.763

Tried 1.3.763, but no changes. Some ads get blocked, most of them are the image ads. But Youtube flash ADS are still there, popups still arrive... If I disable Internet Download Manager addon and restart IE, they are all gone. As a temporary fix, I keep IDM addon disabled until I need it...

I think the IDM addon starts before ABP addon and this is the problem. I looked for a solution to delay IDM, but this is not possible...

ABP makes a call IInternetSession::RegisterNameSpace to handle 'htpp' and 'https' requests. There are known limitations with this mechanism. Among them is that "only the last handler to be registered is active". Download managers often use the same mechanism. While I don't know if IDM does, there's a good possibility that it does, and this may account for the behaviors reported.


RegisterNameSpace method on MSDN

  • Resolution set to fixed
  • Status changed from new to closed
  • Summary changed from ABP not working with IDM addon enabled to ABP not working with other addon enabled

Due to architecture of IE plugins this probably won't fixed.
