It is very good extension! I recommended! It only misses a star (I would prefer to miss half a star actualy) just because I would like to see 2 improvements in order to be perfect:
1) I would like to have the option for faster translation (double click on a word instead of right click and then choose the translation) 2) The ability to translate a word when I am in reader's view which I use a lot (although I don't know if it is possible)
1) It can translate on a double-click! Just navigate to settings to turn it on! 2) Unfortunately, we can't translate in the Reader Mode due to FF restrictions.
