Changing theme programmatically

MrBallistic · 2025-06-13T13:16:03+00:00

I use "gsettings set org.gnome.desktop.interface gtk-theme <...>" to control whether my system is light or dark mode, and while some apps work with gtk, others appear to have their own system.

That's why I'm looking for a bash command which can help me do just that for Zotero (to avoid manually having to change the theme in Settings).

# Systeminfo

Assuming you mean light/dark mode and not the reader theme:

With Zotero closed, it would be setting browser.theme.toolbar-theme = 0 (dark) / 1 (light) / 2 (auto) in prefs.js in the Zotero profile folder.

With Zotero running, you'd have to script it (using BBT's debug-bridge, perhaps) and change that pref with Zotero.Prefs.set('browser.theme.toolbar-theme', [value], true).
