Actual results:

Reported column number is 5 for both tested scripts, in both stack and columNumber field of the Error object.

Hello Hugo, I managed to reproduce this issue In Firefox Release 66.0.3 using your html example, but In our latest Beta and Nightly builds I'm getting different column numbers 12 respectively 21 and I'm not sure if they are correct or not, Can you please try our latest Beta and Nightly builds you can find them here :

https://nightly.mozilla.org/

https://www.mozilla.org/ro/firefox/channel/desktop/

and retest this issue to see if its been fixed already by our developers.

I think this issue has been fixed in our latest builds and since the reporter didn't respond anymore I'm inclined to think its been fixed on his side as well. If the issue still occurs in our Beta or Nightly builds please reopen this issue.
