Firefox Add-on: init event is not emitted

[vmangelovv]

Describe the bug
On Firefox the function onInit is running the real initialization is not happening.
I think this is bug to work out.
This is my ex.:

<qrcode-stream @decode="onDecode" @init="onInit">

and the init func:

onInit (promise) {
promise.then(() => {
/* ... */
}).catch(error => {
console.log(error)
})
}

I tried init() and init($event) but don't work

2 libraries have been used to fix the problem, but unsuccessfully.

First

Second

P.S. In chrome works perfectly.

To Reproduce
Steps to reproduce the behavior:

1. Go to Account menu
2. Click on Create a vault for AirGap
3. Next
4. Link vault

Expected behavior
The browser should open new page, so the user can allow or deny camera permission. In Firefox this is not happening.
