what I would like to do is simply start over. get rid of the apps I did download and then, with a better understanding of exactly what I am doing, start over. the way things are currently I find this version unusable. I mean, I can't function with things as they are! downloaded apps I think which are beyond me.

don't even know where or how to begin. this is the kind of help I need; what do I do? I need very specific instructions on this. Adblock is fine. not sure if I want Scripts. or Browserprotect. also have Ghostery, enable Javascript, enable/ disable Java, enable/ disable flash, e/ d Silverlight, e/c Cookies, auto load pages, e/d animated images, toggle style, and Firebug 1.7.3. some are likely for web developers which I am not... last one I have would be Translator.
