1146132 - content scripts don't attach to intercepted frame on firefox nightly with e10s

Status: RESOLVED DUPLICATE of bug 707624

(Add-on SDK Graveyard :: General, defect, P1)

Description

[winhowes]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:36.0) Gecko/20100101 Firefox/36.0
Build ID: 20150320202338

Steps to reproduce:

I'm writing a FF addon where when a particular url is loaded in an iframe I intercept the request and load my own content instead by redirecting to a data URI and attaching a content script to the intercepted iframe. This works brilliantly on every version of FF except nightly with e10s enabled (it works with e10s disabled).

Interception Code:

function requestListener(event){
    event.subject.QueryInterface(Ci.nsIHttpChannel);
    let url = event.subject.URI.spec;
    if(url == particularURL) {
        event.subject.redirectTo(Services.io.newURI("data:text/html,CONTENT",null, null));
    }
}

Page Mod code:

pageMod.PageMod({
    include: ["data:*"],
    contentScriptFile: [data.url("myScript.js")],
    contentScriptWhen: "ready",
    attachTo: ["frame"],
    onAttach: function(worker){
        console.log("Attached"); //doesn't run with e10s
    }
});


Actual results:

In FF nightly with e10s enabled, the content script doesn't attach to the newly loaded frame.


Expected results:

The content script should attach to the newly loaded frame (this works with e10s disabled)

[Dave Townsend [:mossop]]

Can you give a fuller testcase here, how is requestListener being called for example?

Comment 2

[winhowes]

requestListener is being called like this:

var events = require("sdk/system/events");
events.on("http-on-modify-request", requestListener);
