I liked the (old) way it translated the text I highlighted, that is near the translated text, instead of getting it in a separate bottom toolbar. This consumes some precious space.
Two little strange behaviors to tell about:
1. "Sorry, text is too long to translate "appears when I select a "space"
2. My cursor disappeared after several translations .
In all, I can't surf without having this add-on installed and properly running, so thank you for the great job.
