I want the browser to allow a website to re-direct it to another window or website automatically. As it is now I get a message that says Firefox prevented re-direct. I read that can be changed in the "about.config" section but I don't know how to find and open "about.config"

Hello alfredman,

This is how :

Type in the address bar   about:config   (press Enter)
(ignore the warning)

Type in the searchbar and look for the preference :

accessibility.blockautorefresh :

its value needs to be set to   false   to turn it OFF

its value needs to be set to   true  to turn it ON

(after a value has been changed :   close and restart Firefox)
