Firefox extension is not working as expected

[sadorowo]

What happened?

Every time when Yin&Yang extension is trying to load app settings, an error happens.

Error is triggered by these lines of code:

The theme is finally not changing.
I'm using latest Arch with updates applied, and Firefox installed using pacman.

Version

3.3

How did you install Yin & Yang?

AUR

What desktop environments are you seeing the problem on?

KDE

Which plugin causes the issue?

Firefox

What software version do you use?

Firefox 125.0.2, 64bit

Relevant log output

I don't have any logs

Have you installed Firefox natively or as a Flatpak?

[sadorowo]

I think I installed it natively, I just used sudo pacman -S firefox

Do you have this json file under /usr/lib/mozilla/native-messaging-hosts/?

[sadorowo]

yeah, but I noticed I have the communicate.py file mentioned in path in other location.
In /opt/yin-yang/ I have 3 directories: designer, resources and yin_yang.
I have communicate.py file it in /opt/yin-yang/yin_yang/communicate.py

[sadorowo]

I tried to reinstall Yin&Yang using

yay -R yin-yang

/opt/yin-yang got removed, then

yay -S yin-yang

but the issue still hasn't been solved.

For some reason I have the communicate.py in other location than it should be - I think this is causing an issue, especially because I'm getting "Error while loading application translations" on startup, so it may be related to incorrect path.

Have you managed to fix it? On my end the YinYang extension has no effect on the current theme.

[sadorowo]

no, I'm waiting for response from maintainer :/

@l0drex any updates?
I notices 2 things:

1. When I'm running communicate.py manually I'm getting this error:

❯ python3 /opt/yin-yang/yin_yang/communicate.py
Traceback (most recent call last):
  File "/opt/yin-yang/yin_yang/communicate.py", line 15, in <module>
    from .meta import PluginKey
ImportError: attempted relative import with no known parent package

However, when I run this script with -m flag everything works fine.
I don't know if Mozilla is running the script with this flag

2. There are 2 different paths:

• path in native-messaging-hosts/yin_yang.json: /opt/yin-yang/communicate.py
• real file path: /opt/yin-yang/yin_yang/communicate.py

I tried installing Yin-Yang from both AUR and from source. Unfortunately Firefox support is still broken for me.

Experiencing the same problem,
Firefox installed natively on Fedora KDE

as a workaround, I have this extension installed for now : "automaticDark - Time-Based Theme Changer"
