Edit2:
Inzwischen wird das Deepl-Icon auf X-com wieder direkt angezeigt. Deshalb ändere ich (wie versprochen) meine Bewertung wieder auf 5 Sterne. Danke für den Fix! ;-)

In English:
The Deepl icon is now displayed directly on X-com again. That's why I'm changing my rating back to 5 stars (as promised). Thanks for the fix ;-)

Edit:

Thank you for your feedback. I had exactly the assumption that this (Change from Twitter.com to X.com) was the cause. I'll leave the 1 star rating so you can read my edit. Next week I will change it to 5 stars. As I said, that was just to get your attention. Because basically I am very happy with Deepl. ;-)

-----------------------------------------------------------------

Seit ein paar Tagen wird auf "X" das Deepl-Symbol bei den Posts nicht mehr automatisch angezeigt. Man muss den Text erst markieren damit das Deepl-Icon erscheint. Ich benutze Firefox auf Windows 11.
Ich bewerte bewusst mit nur 1 Stern damit die Entwickler es beachten und ich vielleicht hier eine Rückmeldung bekomme.

For a few days now, the Deepl icon has no longer been displayed automatically on “X” posts. You first have to select the text for the Deepl icon to appear. I use Firefox on Windows 11.
I deliberately rate with only 1 star so that the developers pay attention to it and I might get some feedback here.

the best until now. deepL helps me to make my work efficiently and stress free.

Great

fantastische vertaling

Good extension with good translation quality. Works quickly and easily. This message was translated with it x)

as

Лучший переводчик. Но хотелось бы иметь тёмную тему и возможность переводить выделенный текст через кнопку в меню, которое появляется нажатием правой кнопки мыши по выделенному тексту.

反应太慢

It is good that it allows writing, but full-page translations are not allowed for free in distinction with other extensions like TWP and that's bad. Also it bothers that this extension is not monitored for security.
