Link-based popup blocking stopped working in Firefox 79
Background
Starting with Firefox 79, <a target="_blank">
links imply rel="noopener"
, and documents created with the noopener
flag aren't reported through webNavigation.onCreatedNavigationTarget
on Firefox, hence are ignored by Adblock Plus' popup blocking logic.
Steps to reproduce
- Open https://testpages.adblockplus.org/en/filters/popup on Firefox 79 or higher.
- Add filter
||testpages.adblockplus.org/testfiles/popup/link.html^$popup
to the extension. - Refresh the test page and click
Trigger link based popup
Observed behavior
The popup is not blocked.
Expected behavior
The popup should be blocked.
