I have a simple question that I cannot get an answer to in any of my searches on the web. I have Windows XP, and Firefox is my choice for using the Internet.
I have updated some of my plug ins, but now I am at the point where I am asking you what plug ins do I absolutely need? Can I get rid of some of them which others do the same thing?
I use Facebook, Twitter, YouTube, ITunes, but I do not watch movies on my PC.
I need to know what is absolutely necessary, and what is not?
