I have some modifications I want to make WITHOUT installing extensions.
eg: max width of tab and height of menu,
In previous versions you could have it done via:
Since FF4 it should be done with CSS. Now I searched the default theme:
C:\Users\wetcat\AppData\Roaming\Mozilla\Firefox\Profiles\feriz.default and C:\Program Files (x86)\Mozilla Firefox
In the second I could find the extension -> theme but without any CSS. In the AppData I couldn't find any CSS or theme folder.
WHERE is the file to create or alter the CSS??
I'm using Firefox 11.
