Trying to find the same theme that I had on another machine. Is there any way to determine which theme is installed on my browser?

If Firefox is running, sure: open the Add-ons page using either:

  • Cmd+Shift+a (Windows: Ctrl+Shift+a)
  • "3-bar" menu button (or Tools menu) > Add-ons

In the left column, click Appearance. The currently active theme is the only one that's not grayed out. It may have a More link to find it on the Add-ons site.

Are you referring to a lightweight theme (Persona) that styles the user interface with a background image or do you have a complete theme that also provides toolbar icons?

The data of all installed Personas and its background color and text color are stored in the lightweightThemes.usedThemes pref in JSON object format ({"id":"#","name":"xxx",...}). The first entry of that pref is the currently selected Persona.

You can find this data in the prefs.js file in the profile folder.

Thank you so much for such quick and to-the-point assistance!
