Funktioniert soweit wie gewünscht, eine sehr nützliche Erweiterung.
Leider ist die Pro-Version für Ottonormal viel zu teuer.

doesn't show any translation

good, easy to use for the selected text

It just works! No kidding, you almost don't notice this add-on, just highlight the text, click on the button, and it works!

I confirm the malfunction warning issued by the previous user: once installed, the add-on didn't work on my machine either... the small icon didn't popup near the selected text. Not understanding why, I went to the add-on's permission settings and discovered that the "Access your data for all your websites" permission (in French on my machine) had remained deactivated. I activated it manually... then I refreshed a page that was already open in any other Firefox tab, and tried a translation again: this time it worked, the small icon poped-up and the translation appeared when clicking the icon. And since then, everything works perfectly. I don't know whether it's Mozilla that refused to allow this option to be activated by the add-on installer or whether it's an oversight in the add-on installer itself. Anyway, everything now works perfectly.

Not working as intended.

harika

paid for the pro ver. and downloaded it to my new imacs. not working at the moment.

It's a good extension. It will be the best if you add feature to automatically translate highlighted text without extra interactivity like pressing a button to translate

really fast, and good results.

Best and easiest translator I have used.

Mükemmel!

It works very well, but I ran into a bug not long after installing this. I'm on Twitch often and watch a lot of streams, but with this enabled, I can't open the emote menu--the icon for writing obstructs the emote button. Even with the writing icon turned off, the emote button isn't working! I use them often, so unfortunately I need to uninstall this until it's fixed.
