Tor browser is using light theme (breeze?) although in system settings i set arc-darker as theme for gtk apps. I tried setting GTK2_RC_FILES to my .gtkrc-2.0 but it didn't help. Is there a way to make it use arc theme, like, for example, firefox does?

I installed torbrowser-launcher version 0.2.9-2 which provided me with the Tor browser which itself is based on Firefox 60.3.0esr:

About Tor browser

The point to note is that Firefox is and has been a gtk3 application since Firefox 46. So your gtkrc-2.0 settings will not be effective.

I suggest you look at System Settings > Application Style > GNOME Application Style and make a suitable choice there.

GTK3 theme settings

  • I tried those settings, but they doesn't seem to affect tor browser, but they do affect all other gtk apps, though. – fredboy Nov 21 '18 at 14:24
  • Well, now that you know that .gtkrc-2.0 has nothing to do with Firefox, I hope you'll be able to figure things out. I don't have Tor on my Kubuntu system to help you. – DK Bose Nov 21 '18 at 14:37
