Mozilla.cfg not forcing all lockPref / not changing default value for some preferences
Hello Everyone,
Im implementing DOD compliant settings to Mozilla for our enviroment. I am currently in the testing phase - making sure its all set before deployment, Heres where the fun begins.
Ive done the usual - Place the mozilla.cfg in C:\Program Files\Mozilla Firefox Place the autoconfig.js in C:\Program Files\Mozilla Firefox\defaults\pref
and have set the lockPref accordingly for each finding. The issue is that some are being set correctly while others arent being changed at all and most changes arent locked. I have edited the config file to not include the comments (except the top one of course) and changed the \n\r and \r\n to be only \n for the entire file so formatting should not be the issue. I have also changed all commas to match the ones settings that work (no luck) - “” rather than ""
These are working - but doesnt have the lock image
lockPref(“security.default_personal_cert”, “Ask Every Time”; lockPref(“signon.rememberSignons”, false); lockPref(“toolkit.telemetry.archive.enabled”, false); lockPref(“browser.search.update”, false); lockPref(“browser.contentblocking.category”, strict); lockPref(“privacy.trackingprotection.cryptomining.enabled”, true); lockPref(“security.tls.version.max”, 4); lockPref(“dom.disable_window_flip”, true); lockPref(“network.protocol-handler.external.shell”, false);
These have Lock image and cannot be changed -working as it should
lockPref(“toolkit.telemetry.enabled”, false);
These are not working:
lockPref(“extensions.update.enabled”, false); lockPref(“dom.event.contextmenu.enabled”, false); lockPref(“extensions.htmlaboutaddons.recommendations.enabled”, false); lockPref(“datareporting.policy.dataSubmissionEnabled”, false); lockPref(“security.ssl3.rsa_des_ede3_sha”, false); lockPref(“security.enterprise_roots.enabled”, true); lockPref(“security.tls.version.min”, 2); lockPref(“browser.formfill.enable”, false) lockPref(“signon.autofillForms”, false); lockPref(“dom.disable_window_move_resize”, true); lockPref(“devtools.policy.disabled”, true);
These dont even show up in firefox:
lockPref(“xpinstall.enabled”, false); lockPref(“plugin.disable_full_page_plugin_for_types”, PDF, FDF, XFDF, LSL, LSO, LSS, IQY, RQY, XLK, XLS, XLT, POT, PPS, PPT, DOS, DOT, WKS, BAT, PS, EPS, WCH, WCM, WB1, WB3, RTF, DOC, MDB, MDE, WBK, WB1, WCH, WCM, AD, ADP); lockPref(“dom.disable_window_open_feature.status”, true); lockPref(“browser.newtabpage.activity-stream.enabled”, false)
below is the config file

If I look closely to your above posted code then I notice you use Unicode quotes (”: Éd;) and not the ASCII quotes (": ), so you need to make sure that all quotes are the latter.

The pref you posted under "These dont even show up in firefox:" are no longer supported in current Firefox releases. You can check about:config to see what prefs are suprorted or search the source code via https://searchfox.org/mozilla-release
Note that you can also use policies.json to deploy Firefox settings and there is support for quite a few prefs.
Also, this preference:
lockPref(“plugin.disable_full_page_plugin_for_types”, PDF, FDF, XFDF, LSL, LSO, LSS, IQY, RQY, XLK, XLS, XLT, POT, PPS, PPT, DOS, DOT, WKS, BAT, PS, EPS, WCH, WCM, WB1, WB3, RTF, DOC, MDB, MDE, WBK, WB1, WCH, WCM, AD, ADP);
Is missing quotes for the types.
If you email the actual config file to me at mkaply at mozilla.com, I'll fix it up
Side note, I'm working with the DOD to update the STIG. Hopefully updates out soon and will remove all these old prefs and switch to using policies.
I worked on this via email with Royal and we also found some unquoted strings. I marked the quote problem as the fix since that was the primary problem.
It's still not working locally for them (although it is for me), so I think they are having a separate issue. I'll continue to help as needed.
