Hello!

If the extension is installed, the extension is the dictionary.

You just need to turn it on:

See points:
3.1 & 3.2

And remember that to use it in Thunderbird, you will need to install it there.

To use it in Firefox, you need to install it there.

(to use on both, you need to install on both).
