==Early history==
On April 20, 1999, it was reported that Mozilla, at the time the open-source arm of [[AOL]]'s [[Netscape|Netscape Communications]] division, had announced the commencement of "an instant messaging and chat project with the stated goal of supporting a wide variety of chat protocols, including "the venerable Internet Relay Chat". Other companies were also developing chat systems. {{" '}}We recognize that there's a lot of interest in the instant messaging space,' said AOL spokesperson Catherine Corre, referring to the Mozilla project.

==Features==
ChatZilla runs on any platform on which SeaMonkey can run, including [[OS X]], [[Linux]], and [[Microsoft Windows]], and provides a "consistent user interface across the board."<ref name="Golbeck16">{{cite book |chapter=Hack #4, IRC with Chatzilla |title=IRC Hacks:100 Industrial-Strength Tips & Tools |editor=Mutton, Paul |first=Jennifer |last=Golbeck |publisher=[[O'Reilly Media]] |page=16 |year=2004 |chapter-url=https://books.google.com/books?id=MbHAnBh9AqQC&pg=PA16|isbn=978-0-596-00687-7}}</ref> It can also be used as a standalone app using [[XULRunner]].<ref>Reyes, Mel (2005).

It contains most general features of IRC clients, including connecting to multiple servers at once, maintaining a built-in list of standard networks, searching and sorting of available channels, chat logging, [[Direct Client-to-Client]] ("DCC") chat and file transfers, and user customization of the interface.<ref name="homepage"/><ref>{{cite book| title=Fedora 12 User Guide |author=Fedora Documentation Project |page=71 |year=2009 |publisher=Fultus Corporation |isbn=978-1-59682-180-4 |url=https://books.google.com/books?id=iUFdxIsBgZ8C&q=chatzilla&pg=PA71 }}</ref>

ChatZilla is included with [[SeaMonkey]]<ref name="CWAlderman">{{cite magazine |title=Review: SeaMonkey 1.1.8 for the Mac |first=Nathan |last=Alderman |date=February 29, 2008 |magazine=Computer World |url=http://www.computerworld.com/s/article/9065999/Review_SeaMonkey_1.1.8_for_the_Mac |access-date=October 11, 2010 |archive-date=October 10, 2012 |archive-url=https://web.archive.org/web/20121010021924/http://www.computerworld.com/s/article/9065999/Review_SeaMonkey_1.1.8_for_the_Mac |url-status=dead }}</ref><ref>{{Cite web|url=http://www.seamonkey-project.org/doc/features|title=SeaMonkey: Features|access-date=2009-09-10}}</ref> and was available for download to other Mozilla-based browsers such as [[Mozilla Firefox|Firefox]] as an [[List of Firefox extensions|extension]].<ref>{{cite web |title=ChatZilla – Add-ons for Firefox |url=https://addons.mozilla.org/en-US/firefox/addon/chatzilla/ |website= |date=22 May 2018 |archive-url=https://web.archive.org/web/20180522074105/https://addons.mozilla.org/en-US/firefox/addon/chatzilla/ |archive-date=22 May 2018 |url-status=dead}}</ref> It could also be run in a tab in Firefox.<ref>{{cite web|url=http://chatzilla.hacksrus.com/faq/#inatab|title=Frequently Asked Questions - ChatZilla|work=hacksrus.com}}</ref>

==Plugins==
ChatZilla offers many plugins, which extend the functionality in the user-experience of the add-on.<ref name="RDM Software">{{cite web|last=Marshall|first=Rob|title=ChatZilla Plugins|url=http://chatzilla.rdmsoft.com/plugins/|access-date=19 May 2013}}</ref>

Some of these plugins include:
* [[TinyURL]] – replaces long URLs (typically those with more than 80 characters) with TinyURL links
* googleapi – searches Google and displays the top result
* cZiRATE – shares the song the user is currently listening to on iRATE Radio

==WebExtension==
The introduction of [[Firefox Quantum]] (version 57) has dropped the support of legacy add-ons that utilized XUL and XPCOM, and so has stopped ChatZilla from working inside Firefox thereafeter.<ref>{{cite web |url=http://chatzilla.hacksrus.com/ |archive-url=https://web.archive.org/web/20200315134013/http://chatzilla.hacksrus.com/ |archive-date=2020-03-15 |title=Home |work=ChatZilla |date=2017-11-15}}</ref> Work has begun to move the code to a [[WebExtension]].<ref>{{cite web |url=https://bugzilla.mozilla.org/show_bug.cgi?id=1322442 |title=1322442 Convert ChatZilla to a WebExtension |work=Bugzilla}}</ref>

==Reception==
Reviews of ChatZilla have varied from enthusiastic, in the case of users familiar with IRC, to  unimpressed, for reviewers more accustomed to other chat client user interfaces.  A 2003 review in ''Computers for Doctors'' of Mozilla 1.0, referred to IRC client applications as "not very user-friendly, and the same goes for ChatZilla. You won't find any pop-up icons, or happy little noises telling you somebody wants to chat."<ref>{{cite book |url=https://books.google.com/books?id=Sq6nEWezMeMC&pg=PA164 |title=Computers for Doctors |editor=Thacker, Naveen |publisher=Jaypee Brothers Medical Publishers |year=2003 |location=India |isbn=978-81-8061-176-6 |url-status=dead |archive-url=https://web.archive.org/web/20161221034249/https://books.google.com/books?id=Sq6nEWezMeMC&pg=PA164#v=onepage&f=false |archive-date=2016-12-21 }}</ref>
In 2004, Jennifer Golbeck, writing in ''IRC Hacks'', pointed out its cross-platform consistency, and found it "quick and easy to start using",<ref name="Golbeck16"/> and has "great support for changing the appearance of chat windows with motifs...([[Cascading Style Sheets|CSS files]])."<ref name="Golbeck19"/>

In a 2008 overview of extensions for Firefox in ''Linux Journal'', Dan Sawyer described ChatZilla as an "oldie-but-goodie", "venerable", "with all the trimmings", "handsomely organizes chat channels, logs, has an extensive built-in list of available channels, supports DCC chats and file transfers, and has its own plugin and theming architecture." The application "implements all the standards very well, and for those who prefer to keep desktop clutter to a minimum but still enjoy fighting with random strangers on IRC, ChatZilla is a must-have."<ref>{{cite journal|title=Must-Have Firefox Extensions |issue=170|date=May 1, 2008 |first=Dan|last=Sawyer |journal=Linux Journal: The Monthly Magazine of the Linux Community|publisher=LinuxJournal.com |url=http://www.linuxjournal.com/magazine/must-have-firefox-extensions?page=0,1 |issn=1075-3583 }}</ref>
