firefox keeps giving the message not responding . I get on a site and then when I go to scan down ,

Hey there Nomf and welcome to the Webroot community forums!
 
Sorry to hear your Fox isn't running as fast as he should, he can be a lazy fox at times :(
 
Firefox is known to be a bit of a resource hog on your system, the guys over at Mozilla try to sort hings out through system optimization. I would try to do a Firefox update if possible or complete reinstall ( a complete reinstall is best practice)
 
 
Due to Firefox having some modification abilities, the more your mess with it or programs change it the more it eats up resources on your system, so a complete reinstall should hopefully speed things up for you. I will put a download link here
 
Hope this helps, if not get back to us and we will do what we can, or at least point you in the right direction! 
 
All the best
Brad
