CID image blocking in Thunderbird

[ajk]

Hello,

I'm trying to find a way to block src=cid images in HTML e-mail. I've been using Adblock in Thunderbird and it's working fine for external images, but I've not been able to specify a filter that will block inline attached images.

The URL to the image is in the form "cid:xxxx" where xxxx is an arbitrary string that matches the Content-ID value of an attached image.

I've tried the following filters (and others as well)...
cid
cid:
*cid:*
|cid:*
|cid*

Nothing I've tried has worked. Does anyone know of a filter that will block these images?

If Adblock won't do it, does anyone know of another solution for blocking these in Thunderbird?

Thanks.
Andy

I can't seem to get it to remove anything. how do you configure it?

I don't think I did anything special when installing it. I just installed it and selected the EasyList filter subscription. I was then able to right-click on images in the messages and block them.

The only problem I had was that occasionally I would not be able to create new messages with Adblock installed. I tried uninstalling and reinstalling and eventually found that if I could not create a message I just quit Thunderbird and restarted it and normally I could create messages then. I've not had that problem for a while so they may have fixed it.

I have the latest version of Thunderbird and Adblock. I use Adblock in Thunderbird successfully on Mac OS X and Windows XP. I've been trying to get the CID blocking to work on the Mac OS X version.

Oh, there is something I forgot to mention about the CID blocking problem.

In Thunderbird I can right-click on a linked image and there is a menu option for blocking the image. When I right-click on a src=cid image, there is no image blocking option in the menu.

cid: URLs are in the whitelist because they aren't actually downloaded - they are pointing to attachments in the mail you already downloaded. However, if you still want to block them, you can open about:config (in Thunderbird you go into Options / Advanced / General / Config Editor for that) find extensions.adblockplus.whitelistschemes preference and remove "cid" from the list.

Thanks, I'll give that a try.

It looks like ABP is not getting the "raw" HTML from the e-mail message. It looks like it is getting a processed version that has the URL to the local location of the image. So, instead of seeing the cid: URL ABP is seeing mailbox: or imap:. If that is the case, then it's probably not possible to filter based on a cid URL since ABP will never see it.
