1141732 - [e10s] "This Frame" > "Print Frame…" in remote browser causes unsafe CPOW usage warning

Status: RESOLVED WORKSFORME

(Firefox :: Menus, defect)

Description

[Ian Moody [:Kwan] (UTC+0)]

+++ This bug was initially created as a clone of Bug #1133577 +++

STR:

1) Visit a site with a frame in it in an e10s window
2) Right-click in the frame, and choose "This Frame" > "Print Frame…"

This causes an "unsafe CPOW usage" warning in the Browser Console.

In browser/base/content/nsContextMenu.js:

  printFrame: function CM_printFrame() {
    PrintUtils.print(this.target.ownerDocument.defaultView); <- Causes CPOW warning
  },

It also fails with "Error: PrintUtils.print expects a remote browser passed as an argument if the content window is a CPOW." but mconley asked for a separate bug for that.

Still an issue - would probably be fixed if we started passing around outerWindowIDs instead, a la bug 1146454.

This should be fixed now that bug 1146454 has landed.
