Sup guys I work at a company and I maintain our customized firefox setup. We use userchrome.css to lock down the interface, to prevent people from doing stuff they shouldn't. I upgraded the setup files to Firefox 26, but now it's not copying my defaults anymore!! So I extract the firefox setup file from the main download website. in \core\defaults\pref\channel-prefs.js, I reference my lockdown file, which is in \core\mozilla.js in \core\defaults\profile\chrome, I have userChrome.css and userContent.css, both with my customization I also have \core\override.ini to prevent the profile migrator from coming up. Now when I install firefox 26, none of the defaults are copied to the new profiles, so none of the configs are locked down. If I copy them manually, the lockdown applies. However, it should be copied automatically from the "Defaults" folder, to every new profile. This is not happening anymore. Any ideas?? It used to work fine until the new version. Was this feature removed or something?
