Nice, but a little big. Rated 5 out of 5 stars

Nice addon! And it is restart-less!
But when translating some text, I think the pop-up frame that opens could be smaller and maybe in a corner, so it wouldn't interfere (being in the center of the screen) with the web page. Also being able to scroll the page at the same time as the translation is displayed would be useful :)

This review is for a previous version of the add-on (0.2.1.1-signed).
