Passwords import from Firefox Developers edition

Hello community,

please, has anyone tried to import passwords from the Firefox Developer edition? (I am currently running on 117.0b3 (64-bit)).

Problem: Norton utility will create a JSON file, but when I try to upload, it just says that an error has occured, but no explanation.

I tried to run the utility from the terminal to get some output and it seems like it did not detect my FF.
I won't paste the full output, but basically:
Failed to get Firefox path from registry
...
  File "source\extractors\FFLoginExtractorUtils.py", line 222, in get_firefox_path_from
FileNotFoundError: [WinError 2] The system cannot find the file specified
...
Traceback (most recent call last):
  File "source\LoginImporter.py", line 435, in main
  File "source\LoginImporter.py", line 221, in launch_browser
Exception: Failed to get Firefox path from registry


I tried to locate those files in a try of just manually putting there FF Dev install path, but source\LoginImporter.py, or source\extractors\FFLoginExtractorUtils.py do not exist. It is either compiled inside the exe, or loaded remotely on execution, those folders/files are just not part of the utility.

Does anybody have any workaround?

Thank you!
