Kernel systems are like XP and VIS. XP can be used, but VIS may not.

You can open Firefox first,

Then enter: about:config in the address bar.

After the pop-up window appears, click the corresponding button to enter the setting window.

Right-click a blank space and select New → Boolean.

Then set it to extensions.checkUpdateSecurity in the pop-up window.

Then set its value to false in the window that opens.

In this way, you can avoid security updates and other security modes and use them carefully.

You can also change the security level and set the website as a "trusted site" in Firefox-Tools-Security Options.

However, if it is not necessary, don't change it.
