User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.2b) Gecko/20021016 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.2b) Gecko/20021016 I'm unable to register (and unregister) as app-startup observer in Category Manager at other time than module registration (MozgestModule.registerSelf) in mozilla 1.2b. I've done this change: http://www.mozdev.org/source/browse/optimoz/mozgestService/service/mozgest-service.js.diff?r1=1.1&r2=1.2 and tried to register from preference screen with code: function setStartup(onStartup) { const MOZGEST_CONTRACTID = "@optimoz.mozdev.org/mozgest;1"; const CATMAN_CONTRACTID = "@mozilla.org/categorymanager;1"; const nsICategoryManager = Components.interfaces.nsICategoryManager; var catMan = Components.classes[CATMAN_CONTRACTID].getService(nsICategoryManager); if (onStartup) { dump("*** Mozgest JS Service will be started on Startup\n"); catMan.addCategoryEntry("app-startup", "Mozgest observing Startup", MOZGEST_CONTRACTID, true, true); } else { dump("*** Mozgest JS Service will NOT be started on Startup\n"); catMan.deleteCategoryEntry("app-startup", MOZGEST_CONTRACTID, true); } } But this does niether register my JS service - see http://www.mozdev.org/source/browse/optimoz/mozgestService/service/ - when registered at module registration, nor does it unregister my service in case it was not registered with module. I didn't get any exception, nor JS error. And I'm not sure if it's related, but the module does not reregister itself when it is replaced with newer file, which it did in 1.0 - 1.2a. Reproducible: Always Steps to Reproduce:

Venkman is also unable to unregister its app-startup observer. It appears that the code executes, and removes the observer for the duration of the session, but the observer is never deleted from compreg.dat. The next time mozilla starts up, the observer is still there. The code in question is http://lxr.mozilla.org/mozilla/source/js/jsd/jsd_xpc.cpp#2323
