How to block ads inside an extension?

[jemminger]

I've got the delicious.com extension for chrome installed, and it seems now they're serving ads through it after you bookmark a page.

The ad container is identified by .compose-result .post-bookmark-ad-container, but I can't seem to block it because of the default whitelist chrome-extension-scheme

Example:

Is it possible to block these ads?

Can you show me the URL of the image?

Do you mean the URL of the coupon ad image in the sample above? It looks like it's Google ads:

The ads are being embedded in the delicious.com chrome extension: https://chrome.google.com/webstore/detail/delicious-bookmarks-exten/mnaelnkmidnndgikjbiifihgklnocljd

uBlock does not inject its content scripts on other extension pages. However, you can block behind-the-scene network requests, but this can potentially break important browser functionality, or other extensions. This can be worked around however using dynamic filtering. Here is what you could try, to block the downloading of the ad above but nothing else in the behind-the-scene scope:

• Enable "Advanced user mode" in the Settings pane.
• Add the following rules to the "My rules" pane (click Edit, paste the rules, click Save):
  • behind-the-scene * * allow
  • behind-the-scene pagead2.googlesyndication.com * block
• Make the rules stick by clicking "Commit" on that page.
• Go to the "Whitelist" pane, remove behind-the-scene, apply changes.

See if this works -- I didn't try it, hopefully I got the details right.

Yes! That seems to work. Thanks
