In the preferences Appearence section, there are checkboxes which allow particular modules to launch on startup. It would be nice if you could get chatzilla in there.

Add to the file http://lxr.mozilla.org/mozilla/source/extensions/irc/xul/content/chatzillaOverlay.xul <checkbox id="generalStartupIrc" position="4" label="&ircCmd.label;" accesskey="&ircCmd.accesskey;" prefstring="general.startup.irc"/> which is modified from http://lxr.mozilla.org/mozilla/source/xpfe/components/prefwindow/resources/content/pref-appearance.xul#78 or maybe <checkbox id="generalStartupIrc" wsm_persist="true" position="4" label="&ircCmd.label;" accesskey="&ircCmd.accesskey;" pref="true" preftype="bool" prefstring="general.startup.irc" prefattribute="checked"/> which is modified from http://lxr.mozilla.org/mozilla/source/mailnews/base/prefs/resources/content/mailPrefsOverlay.xul#35 I don't really know if all the pref* attributes besides prefstring are necessary, since they're not present for Navigator yet that check box still seems to work. I just said position=4 so the other numbers wouldn't change, but maybe it should match the Tasks menu?

You can actually set the pref general.startup.chat to true and I believe it works... just no UI. :)

Patch mimicking the way mail/news handles this.

Checked in --> FIXED.

Has this bug really been fixed? I'm using Seamonkey 1.0.2, and when I go to Edit->Preferences->Apperance, there is no checkbox for selecting Chatzilla.

I don't know or care where SeaMonkey 1.0.2 was built from, but the checkbox is on my SeaMonkey trunk build so this is definately fixed. If you have a SeaMonkey that is based on too-old code (as it sounds like, though you may just have something else fucked) installing the latest ChatZilla will likely add the checkbox.
