A few hours ago I installed firefox on an old laptop, logged in, synced my bookmarks etc. Everything went fine except for that this laptop was having the default dark theme and it synced this theme with my main laptop. Now I can't find the theme that my main laptop was using.

I've tried: - Searching for it in about:addons - Searching for it in https://addons.mozilla.org/en-US/firefox/themes/ in my personal profile

How do I find the theme I was using for my main laptop again? it was a default firefox theme which had purple/orange as the main colors.

Is that the builtin Firefox Alpenglow theme ?

You can check the installed themes at the customize page.

You can set services.sync.prefs.sync.extensions.activeThemeID = false on the about:config page to prevent syncing the theme to other devices.

You can open the about:config page via the location/address bar. You can click the button to "Accept the Risk and Continue".
