How to delete the url of local startpage, how to make it as a new tab?
To make the local startpage as a new tab I tried autoconfig.js and autoconfig.cfg but I got a error message when I open the broswer and nothing change. To remove the url from the local startpage I browse the reddit but I couldn't find answer, I want that when I open the browser it show my custom and local startpage without the url appearing.

If you get an error when you use autoconfig, then you can check the Browser Console for more detail.
What code are you using in autoconfig.cfg ?
Note that you need to set general.config.sandbox_enabled to false in autoconfig.js to be able you include JavaScript. You also can no longer import Services.jsm, but have to use a different way.
let Services = globalThis.Services || ChromeUtils.import("resource://gre/modules/Services.jsm").Services;
You can use the autoconfig.cfg file in the Firefox installation folder to initialize (set/lock) preferences and run privileged JavaScript code.
To use Autoconfig, place two files into the Firefox installation directory.
- on Windows, they go into the same directory where Firefox is installed
- on macOS, they go into the Contents/Resources directory of the Firefox.app
The autoconfig.js file that specifies to use autoconfig.cfg is placed into the "defaults\pref" directory where the channel-prefs.js file is located. The autoconfig.cfg file is placed at the top level of the Firefox directory.
- autoconfig.cfg and autoconfig.js need to start with a comment line (//)
- autoconfig.js needs to use Unix line endings (LF instead of CR/LF)
