Can someone look at the mozilla.cfg file I am attempting to use with ESR deployment at our company? I can't see the problem. Edit: pasting without the comments.

I can't attach the actual file, formatting result in this post is horrid. I don't know how to post this properly.

Note there there are quite a few prefs in the file that are obsolete for a very long time (e.g.security.enable_java (52+) browser.history_expire_days).

You can check that without the autoconfig file and search the about:config page.

I haven't tested the file, but a quick look points at the last line that has Pref() capitalized, i.e. should be pref().

  • pref("extensions.autoDisableScopes", 15);

Thanks cor-el, Im not understanding the link, but you are saying check for the presence of all of those values in about:config with an installed vanilla esr install?

and GOOD CATCH that capital P was causing the run-time error. But now you have me wondering about the "obsolete" settings. I got this file from an SCCM posting recomending how to deploy Firefox.. how do I update the obsolete settings?
