Rated 2 out of 5 stars

Works OK but I don't really understand the usefulness. I hoped it would instantly translate the body of an email with one button click. This just pops up Google translate in a tiny modal, and you have to select text first. I can just copy+paste text into Firefox if I want that... Why is this so highly rated?

This review is for a previous version of the add-on (5.0). 

Hello,
Sadly, my addon doesn't have permission to access the email text, it can't translate directly after selecting it.
However, what you can do is select the text / right click / Translate selection (in the context menu) and that will open the translator and enter the selected text inside, so you don't have to copy and paste it manually.
I hope this helps :).
