Add-on & website (https://www.deepl.com/translator) both broken by YesScript2 add-on, even in its no-blocking state (grey).

(DeepL states that it is not Internet Explorer compatible — while I am using Firefox — and advises to use Edge Browser instead).
Even though YesScript2 seems not been updated since 2017.

This has been going on for a few months (last November?) but I don't know if it is due to an update of DeepL or Firefox.

Also reported on the YesScript2 add-on page.
