Could you give the names of those preferences?

user_pref("datareporting.healthreport.nextDataSubmissionTime", "1364605363481"); user_pref("datareporting.policy.firstRunTime", "1364518963481"); user_pref("datareporting.sessions.current.activeTicks", 157); user_pref("datareporting.sessions.current.clean", true); user_pref("datareporting.sessions.current.firstPaint", 1327); user_pref("datareporting.sessions.current.main", 78); user_pref("datareporting.sessions.current.sessionRestored", 1374); user_pref("datareporting.sessions.current.startTime", "1364520337964"); user_pref("datareporting.sessions.current.totalTime", 939895); user_pref("datareporting.sessions.currentIndex", 2); user_pref("datareporting.sessions.previous.0", "{\"s\":1364518963265,\"a\":9,\"t\":45630,\"c\":true,\"m\":78,\"fp\":1311,\"sr\":1358}"); user_pref("datareporting.sessions.previous.1", "{\"s\":1364519097263,\"a\":207,\"t\":1089042,\"c\":true,\"m\":62,\"fp\":1327,\"sr\":1358}");

Thank you.

I don't have those, not sure why not. Have you tried deleting them (after closing Firefox)? Do they come back?

I've deleted them and tehy have reappeared.

Thanks.

Did you check the value of datareporting.policy.dataSubmissionEnabled (default = true) on the about:config page?

edit: This doesn't seem to make any difference in creating datareporting prefs.
I assume that you can only disable the submission and not collecting data.

Thanks.

It just occurred to me that this might be a feature unique to beta/aurora versions of Firefox.

Thanks again.

I'm using Fx 20 candidate.

Thank you.

I'm only using the following entries:

user_pref("datareporting.healthreport.nextDataSubmissionTime", "1368191387214"); user_pref("datareporting.healthreport.service.enabled", false); user_pref("datareporting.healthreport.uploadEnabled", false); user_pref("datareporting.policy.firstRunTime", "1368104987214");
