In Gnome Tweak Tool, I'm unable to change the Shell theme:
Hovering over the exclamation mark shows the following tool-tip: Shell user-theme extension not enabled. I'm using Ubuntu 14.10, and have installed gnome-shell-extensions.
In the newest version of Ubuntu (11.10) when I run from the command line Gtk complains loudly (over several lines) each time a window is opened. The problem is clearly with the theme - if I change the default from Ambiance to High-Contrast this goes away. Some examples:
travis@hydrogen:~$ emacs foo.txt

I like the themes and I don't want to part with them. How can I fix the command line verbosity from Gtk? I can simply hack the command line to filter out these messages, but I really don't like that idea.

Something about the color scheme changed in 11.04, and now it's very difficult for me to tell which tab is the selected one.
On my screen, the colors look more similar the further down I slouch in my chair (i.e. angle of view).
If I change the color scheme the problem is solved, but that solution is too extreme for me. Is there a way to just change the color of the selected tab in terminal, or otherwise make it more prominent?
UPDATE: In 12.10 the accepted solution doesn't work. Can anyone fix it?
I have a dark GTK theme installed in my Ubuntu 10.10 install and a persona installed for Firefox that I also like.
The problem is that Firefox is using my dark GTK theme for items like buttons and text fields on common web pages, and this commonly creates unreadable menus, text areas, and buttons. (white text on white backgrounds, or black text on black buttons).
I don't want to change either theme, because they look great in every other application, and I don't want to have to do something crazy to my Firefox install like use custom user scripts or CSS overrides.
All I want to do is tell Firefox to stop using my GTK theme completely. This appears to be what Google's Chrome browser does and it makes the most sense by far.
How can web developers possibly work around all the possible GTK themes out there?
I want to change an icon of a specific theme. Where do themes save their icons?
