Firefox's look

A little summary of what factors vary the look of Firefox in Linux.

Firstly, there's the Firefox theme. This controls the appearance of the buttons and such in the toolbars at the top. Easy to change: Go to the web page and download one that looks nice. There's a "themes" option in the "Tools" menu.

Secondly, there's the GTK theme currently in use. This will mainly affect things like scrollbars and dialogue boxes. 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:

menubar, toolbox, toolbar, .tabbrowser-tabs {
 background-color: #FFFFFF !important;
}

This example will set the toolbar background to white. Look up hexadecimal colour values if in doubt as to what to replace the FFFFFF value with: They're easy once you get the hang of colours defined as red-green-blue mixes, and you can work in base 16:
Red: FF0000
Yellow: FFFF00
Green: 00FF00
Blue: 0000FF
Black: 000000
etc.

Fourthly, there's your window manager's appearance, but that's not really a Firefox issue ;o) But if you are about to try and improve Firefox's look, it's worth remembering
that whatever Firefox may look like, it will still have your WM's window decorations around it.
