Okay, there's several things affecting the appearance of Firefox:
Firstly, there's the Firefox theme. This controls the appearance of the buttons and such in the toolbars at the top. Easy to fix: Go to the
web page and download one that looks nicer.
Secondly, there's the GTK theme currently in use. This will affect things like scrollbars. You'll need an app like
GTK theme switch to change this. If you don't have any nice GTK themes installed, you'll want to visit somewhere like
Gnome art
Thirdly, something that can be worth knowing about occasionally: Some parts of the toolbars will not be changed by the two above theme changers, which can leave them looking patchy. To fix this, add a line like the following to your userChrome file:
Code:
menubar, toolbox, toolbar, .tabbrowser-tabs {
background-color: #FFFFFF !important;
}
This will set the toolbar background to white. Look up hexadecimal colour values if in doubt as to what to replace the FFFFFF value with.
Fourthly, there's your window manager's window decorations, but that's not really a Firefox issue.
Hope this helps!
