Modifying sorce code of installed add-ons

Add-ons Development
1

Hello,

One of the users of my add-on GroupSpeedDial has a problem that I was not able to reproduce so I asked him to send me console logs from background script and there I saw several lines like this one:

Firefox nedokáže vytvoriť pripojenie k serveru ws://127.0.0.1:1001/?cid=624950170.  background.js:20:122

Translated to English - “Firefox cannot create connection to server ws://127.0.0.1:1001/?cid=624950170. background.js:20:122”.

Now the interesting part is that my production file “background.js” has only one line (so there cannot be error on line 20) and there is no Web-Socket in my whole add-on at all.

So the source code had to be modified. But is this even possible? And for what purpose?

No. It is often the case that the errors belong to another background.js

Thank you.
You were right, I just received more information and indeed it belonged to another add-on (Internet Download Manager).
