Quick TransLation (qtl) add-on for Firefox

https://addons.mozilla.org/en-US/firefox/addon/5641

This is a great Babylon-powered tool for Firefox that allows you to highlight any word in any language and get a translation for it in almost any other language, as well as automatically look it up on Google.

The best thing about it is that it’s free, unlike Babylon 8 (which costs 10 bucks a month).

Cheers:)
