ReferenceError is not defined onpopupshowing and oncommand

[obywatel]

Hi
I have a nice extension that works below firefox 44 version, in higher versions there is a problem.
(It allows me to download all images to one predefined folder):

Code: Select all

When I install extension everything is ok till when I chose File->Save Images To->Option: Browse
1. Here is a problem, popup windows doesn't shows me.. and in console there is a error message:

Code: Select all

ReferenceError: ImgDlII is not defined
onpopupshowing()
 browser.xul:1
 browser.xul:1:1
ReferenceError: ImgDlII is not defined
oncommand()
 browser.xul:1
 browser.xul:1:1

I'm trying to fix it, but till now, I dont have longer any ideas. Maybe someone could check this extension, this is such a big problem or not and could tell me how I can fix it (what to change)?

Probably the error is much earlier, perhaps right when Firefox starts. If ImgDlII doesn't exist then something bad went wrong, like a syntax error.

Or maybe an e10s issue, but you should be in multiprocess mode in Firefox 44.

With e10s I did have to refactor some stuff as pages were loading much earlier then expected. Like I would set stuff up and then wait for load event, however by the time i set stuff up the load event had already been triggered, so I moved everything into the load listener.
