Applications :: Safari Not Connecting To The Internet But Firefox Is?

since i reset my router all my Apple created software is not connecting to the internet. This includes mail, safari, itunes store, software update. But the strange thing is, Firefox works fine.

When i try to load up a webpage in Safari, it hangs on the loading status for about a minute before saying it cannot load. I have also tried removing the wireless network and starting again but the same thing happens.

In network settings it says that the connection to the internet is fine.

I have tried resetting Safari and clearing the cache but i have had no luck.
