Rated 5 out of 5 stars

Excellent extension; I've used it since it was first available in/after FF8However, in the en-US locale, 'Settings', would it be possible to show "Sprawdzaj pisownie" in English? :D

(Fortunately, it was easy to guess, and then find, a translation)

This review is for a previous version of the add-on (0.6.0.7.1-signed.1-signed).
