Hi!

Good add-on but I have got some issue:

When I make search with the Firefox search bar with this site:
https://www.deepl.com/translator

On the website page translation result, I have "+" between words I have entered in the search bar.

For exemple, if I have entered this "Je chante dans la chambre", the website displays "Je+chante+dans+la+chambre".

How to avoid that issue?

Thx you!
