Change themes based on the system theme not working on Ubuntu Linux

[nose-gnome]

Description When Change themes based on system theme is enabled, the extension will change the browsers theme to the specified nighttime theme, even if the system theme is in light mode. This means that the browser theme will continue using nighttime theme indefinitely, regardless of system theme

System Information

• OS: Ubuntu 22.10 running Gnome 43.1
• Firefox update branch: Release (regular)
• Version: 111.0.1

Steps To Reproduce Steps to reproduce the behaviour:

1. Go to preferences
2. Click on Change themes based on system theme
3. See error: After a few seconds theme will change to nighttime (ignoring system theme)

Expected behaviour Theme changes immediately to match system theme, and continue to match system theme whenever system theme changes

Additional context add-on version: 1.4.1

31 is still not fully fixed. On both my systems, only the first time the system theme changes does it change the browser theme. Restarting the browser allows the sync to happen the next time the system theme changes.

It doesnt set the theme on browser launch.

Tested on:

• NixOS with KDE Plasma, Firefox 111.0.1
• macOS 11.7.3, Firefox 110.01 (old)

Both on latest automaticDark 1.4.1

Edit: might deserve yet another issue. seems like different behavior to the issue above - the theme sync is always accurate, just not triggered more than once
