In many of our previous tutorials, we explained about modifying Firefox configuration parameters
You can access Firefox configuration , by opening the page addressed “about:config”
Always, Firefox displays a warning message, and you have to click on “I will be careful, I promise“.
You can suppress this by modifying the variable !
Just open “about:config” and click on “I will be careful, I promise“.
set the value of general.warnOnAboutConfig to false.
this will remove the warning message permanently.
