I was not able to reproduce this issue so far. I tested on Windows 10. I do not have an account on the mozillazine.org website though, so I just tested by login with a fake login/password. 
Do you absolutely need to do a real login to see the issue?

Does the error prevent you to actually log in the site? Or does the site works properly even though an error is logged?

The log you provided shows that the dead object is in DebuggerProgressListener's onStateChange method.

Windows 7/8.1/10
Firefox 53.0 - 57.0a1 (2017-08-20) (32-bit)
A new profile.
1) e10s off ("Tools" - "Options" - "[ ] Enable multi-process Nightly" - disabled!)
2) Not in an anonymous window!

Do you absolutely need to do a real login to see the issue?
- No.
Does the error prevent you to actually log in the site?
- No.

- Just click on the link - "LOGIN" - see an attachment (animated gif).

Or does the site works properly even though an error is logged?
- Yes.

For Firefox 52.0:
TypeError: can't access dead object webbrowser.js:2508:1
("if (evt.target == window.document) {")
Flags: needinfo?(janekptacijarabaci) → needinfo?(pbrosset)
Thanks!
I was able to reproduce this issue on Windows 10, Firefox 57, with a new profile, and a non-e10s window.
The error looks different between 52 and later versions because we moved the code to a different file, but it seems to be the same error.
