Description (last modified by sebastian)

Adapted from


Windows + Vista 64bit + Opera + English
ABP version Adblock Plus Version

How to reproduce

  1. Got to
  2. Enter "Purifier" into the search field
  3. Open the "More" dropdown
  4. Click the ABP icon and choose "Block Element"
  5. Click on the "Books" item

Observed behaviour

The "Books" menu item is highlighted in yellow, but when clicked the "Block Element" dialog doesn't open, but the page navigates to the book search.

Expected behaviour

The page's event handler shouldn't be triggered, that no navigation happens, but the "Block Element" dialog shows up. This can be achieved by positioning an invisible click trap element over the highlighted element.

I can no longer reproduce this issue as described. However, this is most likely just because the Google website changed a lot in 3 years. But the document cancelling event listeners, the "Block element" dialog relies on those events, might still cause side effects.
