#3375 closed defect (fixed)

Issue reporter doesn't create a screenshot in E10S mode

Reported by: trev Assignee: trev
Priority: P3 Milestone: Adblock-Plus-2.7.1-for-Firefox
Module: Adblock-Plus-for-Firefox Keywords: e10s

Blocking: #3486 Platform: Firefox
Ready: yes Confidential: no
Tester: Ross Verified working: yes
Review URL(s):


This is a follow-up issue to #2809.


Adblock Plus
Firefox 45.0a1
"Enable multi-process Nightly" checked in Firefox Preferences

How to reproduce

  1. Go to
  2. Click ABP icon and choose Report issue on this page
  3. Select "Adblock Plus doesn't block an advertisement" and click "Continue"

Observed behaviour

No screenshot of the page is being displayed.

Expected behaviour

A screenshot of the page is displayed so that one can mark the problem there.


canvas.drawWindow() won't accept an CPOW as window parameter. In the multi-process scenario our code isn't running in the same process as the content window so a CPOW is all we've got.

What to change

Move screenshot creation into the content process.
