Using for a couple of weeks and I already can't live without it. This extension is a game changer for Firefox and deserves a lot more attention. The in-situ translation and performance is far superior to using the google translator website (like every other add-on), in addition to supporting alternative services. I use it a lot when dealing with online bureaucracy, since I don't speak the language in the country I'm in. So the clear privacy policy is important and I would like to see it verified and recommended by Mozilla soon. Also, it would be great to know what happens when filling in forms and other text boxes. Can the data ever be unintentionally altered by the extension? Besides this my only wish is that some day it supports PDF as well. Excellent work!! Seriously, F*ing awesome!
