trying to lock settings in about:config

I'm trying to lock the settings in about:config. I changed the settings, created the mozilla.cfg file, created the all.js file, placed the mozilla.cfg file in > Contents > Resources. I placed the all.js file in > Contents > Resources > defaults > pref. For simplicity sake the mozilla.cfg file is:

// lockPref("browser.startup.homepage", “”);

I converted to cfg using the tool here:

The all.js file looks like this:

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

It was created in TextEdit in plain text.

You still do not have quotes like " ("), but have “ (“)

You no longer have to use to bit shift (rotate 13) and you did already disabled it via general.config.obscure_value = 0

I don't know if the files need to be in > Contents > Resources or in > Contents > MacOS

You need to use normal quotes in the mozilla.cfg file and not special quotes (“) like show in your example.

lockPref("browser.startup.homepage", “”);
lockPref("browser.startup.homepage", "");

I changed all of the quotes in mozilla.cfg to single (') and moved the file into the MacOS folder, restarted Firefox and in about:config the status is still coming up as "user set" and not "locked."

Any other ideas?

You need to use double quotes (") as you see in the prefs.js file.

Do you see any errors in the Browser Console (Firefox/Tools > Web Developer)?

You can try the samples files that I posted in this post as a data URI:

I'm not too familiar with the browser console but it didn't look like there were any errors.

I created a local-settings.js file, added that to the pref folder (removed the all.js file) and now I'm getting "Configuration Error - Failed to read the configuration file. Please contact your system administrator." I tried creating the cfg file from either rich text or plain text and I receive the error.

That message means that the local-settings.js file is found and processed, but that the mozilla.cfg file is missing (i.e. not found in the correct location) or that there is a problem with the file.

Thanks for the reply.

The cfg file still reads:

// lockPref(“browser.startup.homepage”, “”);

I created the file in plain text in TextEdit, renamed it as mozilla.cfg and placed it in the MacOS folder. When I try opening Firefox I receive the previously-mentioned error.

I tried moving the mozilla.cfg file to the Resources folder, opening Firefox but it instantly closes without any error messages.

Haha I had no idea there were 2 different types of "s! Copying yours into the file worked perfectly, thanks for your help!

i have almost the same problem: lockPref not working my case: local-settings.js (in /usr/lib/firefox/defaults/pref) pref("general.config.filename", "mozilla.cfg"); pref("general.config.obscure_value", 0);

mozilla.cfg (in mozilla.cfg /usr/lib/firefox) // lockPref("ui.trackpoint_hack.enabled", 1); lockPref("general.autoScroll",true);

there is no lock in about:config. i forgot to mention that it use to work 1-2 months ago. today i had to use/resintall linux again and is not working anymore

Are you sure that the files are in the correct location and that you are starting this version of Firefox?

Is the channel-prefs.js file in this folder as well?

Do you see the general.config.filename;mozilla.cfg pref on the about:config page

If you temporarily rename the mozilla.cfg file then you should get an error message and won't be able to start Firefox if the local-settings.js file is working.

ah sorry it was my fault. the files are in the right place. the problem WAS that only the root user had access to them. after allowing other users to read the files everything works again.
