Dear Sirs, i love my firefox. and I want to use more of what you offer to protect myself, and know how to clean my laptop so that it is not slow starting up, and how to track trackers, cookie and the like, and know in simple plan text what you are talking about so we know what we are doing, what files mean, and what you recommend as the best action. preety much real learner basic stuff like ie information for idiots, so i dont delete or clean files that i need and should leave alone. i dont play games , some times go to youtube for info, and a bit of face book, can not understand what makes this machine so slow, what am i do wrong and how do i put it right, I am in my 60s so never learnt the basics ect, I want to learn what to do, and what the words you use mean. kindest regards Karen
