<h1>Let a Hundred Browsers Bloom</h1>
<p>The recently released <a href="http://wp.netscape.com/eng/mozilla/ns7/relnotes/7.html">Netscape 7</a> may be the most well known
browser built with Mozilla, but it certainly is not the only one. Mozilla is being used as a framework to create many different types of
applications including OEone's <a href="http://oeone.com/products/desktop.html">HomeBase DESKTOP</a>, ActiveState's <a
href="http://activestate.com/Products/Komodo/">Komodo IDE</a>, and <a href="http://www.mozdev.org/projects.html">all of the projects</a>
hosted on mozdev.org. People are also using Mozilla to create their own custom browsers <i>[link to brian's article]</i>. This article
provides a survey of most currently available Mozilla browsers, so you can try them out and find the one that works best for you.
<h2>Why Do We Need More Than One?</h2>
<p>One of the benefits of Open Source development is that it prevents someone from having to reinvent the wheel whenever they are working
on developing something that has been done before. Since the Mozilla community is already working on a browser, wouldn't it be better if
everyone just focused on making that browser as good as it can be?
<p>Instead of being a bad thing, the several different browser development projects that are currently underway are one of the Mozilla
community's greatest assets. The simple reason for this is that one browser can not be all things to all people. Each new type of
browser that gets built is filling a need that is not being met by any other existing option. Each new browser that is built also has
the potential to appeal to a whole new audience that will help expand Mozilla's adoption.
<p>Another positive benefit of having multiple browsers is that it helps avoid compromises that don't make anyone happy. AOL is
interested in using Mozilla to create a browser that appeals to novice Internet users, but the Mozilla developers who contribute their
time to the project want to create a powerful browser with a collection of advanced features. If the community is locked into working on
only one browser, then the end result of this development process will be a browser that has a bewildering array of features that don't
appeal to either intended audience.
<p>If one browser can't possibly appeal to beginning users and power users at the same time, why not create two different browsers? For
that matter, why not create as many different browsers as there are different types of users? Since all of these browsers are built
using Mozilla, web developers can create sites using standards such as HTML, CSS and DOM that work well with all of these browsers and
users can browse the web with whatever tool suits them best. Everyone wins.
<h2>Gecko Based Browsers</h2>
<p>There are two main types of browsers that are built using Mozilla. Some developers choose to create their application using XUL,
Mozilla's cross-platform XML-based User Interface language. Other developers prefer to use just Gecko, Mozilla's rendering engine, and
then create the interface of their browser using one of the toolkits native to a specific platform. There are Gecko based browsers for
each of the major operating systems in use today, including Windows, Linux and Mac OS X.
<p>The goal of the <a href="http://chimera.mozdev.org">Chimera</a> project is to create a best-of-breed browser for the Mac OS X platform
with a user-interface that is as simple and as clean as possible. Chimera uses <a
href="http://www.mozilla.org/ports/fizzilla/Cocoazilla.html">Cocoazilla</a>, a variant of <a
href="http://www.mozilla.org/ports/fizzilla/">Fizzilla</a> that consists of a UNIX back end connected to a Cocoa front end. Since
Chimera uses a native toolkit to create it's GUI it can't run on any platform other than OS X, but since it doesn't use XUL it is
slightly faster than the default Mozilla browser on the same computer. The most recent stable release, <a
href="ftp://ftp.mozilla.org/pub/chimera/releases/chimera-0.4.dmg.gz">version 0.4</a>, is available for download along with <a
href="ftp://ftp.mozilla.org/pub/chimera/nightly/latest-trunk/">nightly development builds</a>.
<p><img src="http://idisk.mac.com/mozilladave/Public/chimera.jpg"><br> <font size="-1">Chimera with sidebar open</font>
<p><a href="http://galeon.sourceforge.net">Galeon</a> and <a href="http://kmeleon.sourceforge.net">K-Meleon</a> are projects that also
have the goal of creating a simple standards-compliant browser using Mozilla's rendering engine. Galeon uses Gecko to create a browser
for the <a href="http://www.gnome.org/">GNOME</a> desktop and K-Meleon uses Gecko to create a Windows only browser. The latest stable
version of Galeon can be <a href="http://galeon.sourceforge.net/download/">downloaded</a> for a variety of Linux distributions. There
are also alpha versions available for <a href="http://galeon.sourceforge.net/galeon2/">Galeon2</a>, which is a new major version of the
browser that takes advantage of the huge changes in architecture in the new GNOME 2 desktop. The latest version of K-Meleon can be <a
href="http://kmeleon.sourceforge.net/download.php">downloaded</a> for Windows and it includes a number of stability and configuration
changes over earlier versions. Other Gecko based browsers include <a href="http://www.muhri.net/skipstone">SkipStone</a> and <a
<h2>XUL Based Browsers</h2>
<p>The other main category of Mozilla browsers include the projects building their applications using XUL. In many ways, these projects
are similar to <a href="http://mozilla.org/themes/download/">themes</a>, but they take the idea of customizing the browser one step
instance, a theme developer can create new images for the buttons in the main toolbar, but a developer can edit the toolbar to add or
remove buttons in their own browser.
<p>One of the first custom browsers, <a href="http://aphrodite.mozdev.org">Aphrodite</a> was created as an alternative to the default
interface that ships with Mozilla. Aphrodite includes a number of it's own themes, including FruityGum, Inferno and two flavors of the
Sullivan skin. The crash recovery system <a href="http://aphrodite.mozdev.org/total_recall.html">Total Recall</a> is also integrated
into the browser. Development work continues on Aphrodite, although currently there isn't a new release that works with the latest
version of Mozilla.
<p><img src="http://www.mozdev.org/sharedimages/sullivan_grape.gif"><br> <font size="-1">Aphrodite with the Sullivan grape theme</font>
<p><a href="http://beonex.com/communicator/">Beonex Communicator</a> is another XUL based browser that is a user-focused browsing suite
that also comes bundled with a mail client and a web page editor. The latest stable version, Communicator 0.8, is available for <a
href="http://www.beonex.com/communicator/version/0.8/">download</a> for Windows and Linux. Some other XUL based custom browsers include
<a href="http://mb.mozdev.org">Project Piglet</a>, <a href="http://mercuryspider.mozdev.org/">MercurySpider</a>, and <a
<p><h2>The Future of Mozilla Browsers</h2>
<p>The browsers that are currently under development using Mozilla are just the tip of the iceberg. One of the most interesting
possibilities for future browser development comes from AOL, the same company that owns Netscape and that is the main sponsor of the
Mozilla community. Currently the Windows version of the AOL client software uses Internet Explorer as the core of it's browser, but
there are indications that this may soon change. If AOL were to switch and use Mozilla in a new version of their software, tens of
millions of people would be exposed to Mozilla.
<p>AOL has already made some moves in this direction. The latest version of the <a
href="http://www.apple.com/macosx/applications/aol/">AOL client for Mac OS X</a> uses Gecko as it's rendering engine. Gecko has also
replaced Internet Explorer in <a href="http://news.com.com/2100-1023-883808.html">CompuServe 7.0</a>, the latest version of AOL's other
online service. The decision to use Gecko in these two offerings are seen by many as ways for AOL to iron out any rough spots before
they move forward with releasing a Mozilla based version of their AOL client for Windows.
<p>Another interesting project to keep on eye on is <a href="http://mozilla.org/projects/phoenix/">Phoenix</a>. There isn't much known
about this yet, but there are some pages in bugzilla and on the mozilla.org site that have some information. It looks like Phoenix is
based off of an earlier project called m/b (short for mozilla/browser) and has a goal to create a user-friendly stand-alone browser that
is free from most of the constraits placed on the default Mozilla browser. Builds of Phoenix aren't available right now, but it is
possible to grab the source from Mozilla's CVS tree and build it yourself right now. There are instructions about how to do this in the
project's <a href="http://lxr.mozilla.org/mozilla/source/browser/README.html">README</a> file.

<p>If none of these browsers look like they are right for you, remember that you can always create your own browser with Mozilla <i>[link
to brian's article]</i>. Each of the projects listed here could use help with testing and development, so you can also contribute by
adding features or fixing bugs to make these browsers even better. This wealth of browser options is a great strength, so let's hope
that each of these projects continue to mature and innovate. Let a hundred browsers bloom so that we can all use the browser that is
right for us.
