Why should I allow ajax.googleapis.com access to my computer?


I read the previous (closed) thread. Lots of guff about jquery, blah, blah. I did not see the answer to why I want these people on my computer. Yes, they are preventing me from logging on to sites I routinely use. But what else are they doing? And what will they do after I permit them access? I am on Firefox 19.0.2 and javascript is enabled in preferences.

Question owner

This seems to explain why someone would want this if they were designing a website. My question is why do I want to allow someone I don't know to have access to my computer if they will not tell me what they are going to do on it? Clearly, I did not allow them access last week and I was able to go where I want. Today the only site I can see blocking me is this ajax thing.
