402 Part VI — Creating Extensions and Themes
http://www.mozillazine.org

All of these sites have dedicated Mozilla/Firefox theme forums for postings. After all, the more
people who know about the theme, the better.
Supporting Different Operating-System Platforms
One of the underlying goals of the Mozilla organization is cross-platform compatibility.
Unfortunately, there is a bug with themes. On themes using native scroll bars (meaning that
the scroll bars are drawn by the operating system rather than themed), the code is slightly dif-
ferent for the Mac operating systems than for all other operating systems. The default theme,
as well as all of my own themes, suffer from this bug. This means that you’ll have to maintain
two versions of your theme: one for Mac users and one for those who use Windows, Linux, and
all other operating systems that run Firefox. I submitted a bug to Bugzilla in October 2003 and
progress has been slow, but it finally looks like a solution may be near. Keep an eye out for
updates at https://bugzilla.mozilla.org/show_bug.cgi?id=222654 for the
most up-to-date information. For compatibility with all operating systems, I recommend mak-
ing both a Mac and a non-Mac version of your theme available to users until bug 222654 is
fixed.
There are quite a few differences between the two scrollbars.css files, so it is not feasible to list
the differences between them at this time. You can obtain a copy of both files by visiting
http://www.hackingfirefox.com/themes.
Hacking Existing Themes
If you wish to modify existing themes, you should be able to do that easily. Now that you know
the process for creating a theme from the default theme, modifying an existing theme will be
much easier. You don’t have to redefine the install.rdf and contents.rdf files, and the directory
structure will already be set up properly for you.
Using the method to extract the contents of the default jar file, do the same for the existing
theme you wish to hack. Then you can go ahead and modify images or attributes in CSS files
as you did when creating your theme. When you finish, you can re-create the JAR archive for
the existing theme. Then replace the unhacked version in your profile folder, using the method
I suggested. After you restart Firefox, your hacked version of the preexisting theme will load
instead of the unhacked version.
Chapter 18 — Creating Themes 403
Summary
This chapter covers the core topics for creating a Firefox theme. The chapter starts by defining
the necessary tools and then moves on to describe the procedure for using the default theme as
a base. Definition of core files, CSS, and image customizations are covered. Package and
deployment of your theme are discussed. Information for supporting multiple operating sys-
tems and to hack existing themes is also provided.
While this chapter covers the basics, there will be a lot of work on your own to customize the
graphics and CSS files to your liking.
