I need a Translation software

I would like for safari to automatically translate any web page that is not english to english. any suggestions or recommendations..

 

If you know that the page you are looking for can be googled, there is very often a translate function on the entry, but I would add that the translations are computer generated and often are very literal and don't make much sense.
I have used this but am always prepared to tidy up the translation by copying into Word and then editing.
It's not a safari answer I know but not having safari it's the best I can think of.
