Oh thanks !
It's unbelievable that thunderbird doesn't have this feature build-in.
My problem was that I must send email in HTML format because the mail server from my company reformat email if it's not in HTMLformat... and add weird spacing in the original email.

Since I can force HTML format for every email with this add on, I don't have this problem anymore.
