1231990 - [e10s] addEventListener("load"...) does not get events in framescript

Status: RESOLVED INCOMPLETE

(Core :: DOM: Content Processes, defect)

Description

[dpp23]

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:38.0) Gecko/20100101 Firefox/38.1.0 Waterfox/38.1.0
Build ID: 20150607203535

Steps to reproduce:

I have a simple framescript:
[code]
addEventListener("load", () => {console.log("LOAD");}, true);
[/code]

I load it by using
[code]
browser.messageManager.loadFrameScript("script.js", false);
[/code]

On Firefox 44 dev edition, if I have e10s disabled, I get a "load" event for every page load. However if I enable it, I stop getting the events.

I am doing something wrong here or is there an actual bug? I thought framescripts are supposed to behave the same with or without e10s


Actual results:

With e10s I don't get any load events


Expected results:

Getting "load" events with or without e10s

Could you attach a minimal testcase (.html) showing up the issue, please.

Is it possible that you call browser.messageManager.loadFrameScript("script.js", false); so early that
there isn't the remote browser yet? Could you try what happens if you pass true as the last param?

load events do propagate to TabChildGlobal both in non-e10s and e10s case.
(TabChildGlobal is the JS global object for the frame scripts)

re-open if a test case is added
