Hello. I have two online banking plugins that I want to stay on "ask to activate" mode (value 1 for "plugin.state.npsf_bb" and "plugin.state.npsf_abn" preferences in about:config) but somehow manage to set themselves back to "always activate" (value 2 for the preferences) every single time I restart Firefox. I had posted this problem before (here: https://support.mozilla.org/en-US/questions/1019124) and even found an acceptable solution, which is was to use the CCK Wizard addon (https://addons.mozilla.org/pt-BR/firefox/addon/cck/) to make an addon (XPI file) for the sole purpose of locking those two preferences and then install it. That really worked, but eventually I found that it was this custom-made addon what was causing malfunctioning in many Google services (couldn't use Drive, nor create new events in Calendar, etc.). So now I am back searching a new solution. Since the solution was to simply lock those two preferences, I looked for a direct way of doing it and found this: http://kb.mozillazine.org/Locking_preferences, which I followed through. I created a mozilla.cfg file with these contents: // lockPref("plugin.state.npsf_abn", 1); lockPref("plugin.state.npsf_bb", 1); and moved it to C:\Program Files (x86)\Mozilla Firefox. Then created a local-settings.js file, with these contents: // pref("general.config.filename", "mozilla.cfg"); And placed it in C:\Program Files (x86)\Mozilla Firefox\defaults\pref. Then I restarted Firefox, hoping it would work, but it didn't. Did I do something wrong? Or maybe are these instructions outdated regarding newer versions of Firefox? I need help here, please... PS.: there seems to be no option to format or embed code here and, to make it worse, this form collapses what I have pasted as the contents of the two files. The first one has three lines: the first is //, the second is lockPref("plugin.state.npsf_abn", 1); and the third is lockPref("plugin.state.npsf_bb", 1);. The second one has two lines: the first is //, the second is pref("general.config.filename", "mozilla.cfg");.

pref("general.config.obscure_value", 0);
pref("general.config.filename", "mozilla.cfg");
