Firefox autoupdates without permission


I need to run an earlier version (version 9.0) on OSX 10.8. Within a day after installation Firefox has updated itself to the most current version. This is a constant problem. I adjusted all of the preferences the support community recommends, and set the below properties in about:config,

app.update.auto - false app.update.enabled - false app.update.silent - false

however, Firefox still updates itself. Help would be greatly appreciated, Thanks.

Additional System Details


  • User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2) AppleWebKit/537.22 (KHTML, like Gecko) Chrome/25.0.1364.152 Safari/537.22

You can use a mozilla.cfg file in the Firefox program folder to lock prefs or specify new (default) values.

Place a file local-settings.js in the defaults\pref folder where you also find the file channel-prefs.js to specify using mozilla.cfg.

pref("general.config.filename", "mozilla.cfg"); pref("general.config.obscure_value", 0); // use this to disable the byte-shift



You can use these functions in mozilla.cfg:

defaultPref(); // set new default value pref(); // set pref, but allow changes in current session lockPref(); // lock pref, disallow changes

You can consider to lock these prefs:

   lockPref("app.update.enabled", false);
   lockPref("app.update.auto", false);

Install/down-load Winpatrol (free program) locate updater for the program you want to use, and disable the up-dater, just for that program.
