Google Translate is fast, but very inaccurate.

Bing is preferred when you need accuracy, but is slower.

There is a web translator for Bing, but it can't translate pages that aren't publicly viewable.

However, someone figured out a way to translate pages with Bing that can translate pages that need authentication, but it's Firefox only.

You can use a bookmarklet instead. e.g.:
javascript:var url=window.location.href;window.location.href="http://www.microsofttranslator.com/bv.aspx?to=en-US&r=true&a="+encodeURIComponent(url);
Just replace en-US with your target locale.
