 // @description    Registers the old-school about:config page to the URL about:cfg. Intended for use with earthlng's aboutconfig module. That module restores the old about:config page, but gives it a long-winded URL like "chrome://userchromejs/content/aboutconfig/config.xhtml" which takes a lot longer to type in and doesn't look very elegant. This script finds the URL for that module and registers it to an about: URL so it counts as a chrome UI page. We're not just faking it, this makes it a bona-fide about: page. That means you can navigate to it by just typing about:cfg in the urlbar, and also means the identity icon will show it as a secure system page rather than a local file. It even means about:cfg will show up on the about:about page! This technically also makes using the aboutconfig module safer, because it denies the document access to some privileged stuff that it would have with a chrome:// URI. For instructions on installing earthlng's aboutconfig module for fx-autoconfig, please see the script description for App Menu about:config Button. This has only been tested with fx-autoconfig, but it may work with xiaoxiaoflood's loader. I don't think it will work with Alice0775's loader but I haven't tested it. Compatible with my appMenuAboutConfigButton.uc.js script. That button will automatically navigate to about:cfg if this script is installed. I recommend editing earthlng's config.xhtml file to remove line 13: title="about:config" This sets the tab title to about:config, which isn't necessary or desirable since we're changing the URL to about:cfg. Without the title attribute, firefox will automatically set the title to the tab's URL, which (with this script) is about:cfg.
