Ubunut 16.04
Chrome 71
Adblock Plus 3.4.1

How to reproduce

  1. Add the custom filter @@||^$document,
  2. Go to
  3. Open DevTools window and switch to "Adblock Plus" tab
  4. Click twice on homepage video to load YouTube frame
  5. Filter list to only show entries with "DOCUMENT" type

Observed behaviour

No such option exists.

Expected behaviour

Option exists and list can be filtered to only show entries with "DOCUMENT" type.

Further information

While we decide in adblockplusui/lib/messageResponder.js which types the user is able to user as a filter, we generate that list in adblockpluschrome/lib/requestBlocker.js.

First, it's questionable whether filterTypes should be used since the "data-type" attribute on each entry corresponds to the request type.

Secondly, filterTypes doesn't contain "DOCUMENT" because neither does browser.webRequest.ResourceType which this list is primarily based on.

We add other items to filterTypes (in lib/requestBlocker.js) that aren't mapped from browser.webRequest.ResourceType, specifically so that they show up here (e.g. POPUP). However, whitelisting-only types (i.e. DOCUMENT, GENRICBLOCK and GENERICHIDE) aren't included.

Back then, I might have thought filtering for whitelisted requests is good enough in that case, also I didn't want to unnecessarily bloat the list of drop down items. Finally, IIRC, you couldn't filter for these types in "blockable items" in the legacy Gecko extension either.

FWIW, the whole filtering UI of the devtools panel isn't great, but it's the best I could come up with for the MVP back then. Maybe it's time to revamp it in a way that scales better with more filtering options.
