Inline translator feedback here:
It works well from right-click context menu, but it works only once from its shortcut key.
It does although I inactivate the other extensions that I have installed.

Firefox version : Firefox 64.0.2
I'm using Windows 10 Home

Good translator but somehow it does not work in reading-mode which is really sad.

Nützlich und stört nicht

Great, but I'd like to see a more minimalistic interface.

Overall good, but shotcuts not working (pressing do nothing; can't assign key combination in options, field became empty). FF63.0.3, Linux

it's good, but can you add option for hover translate? i mean, not only clicking on a word, but just the cursor over the word and shows up the translation.

Was the best translator, the more customizable and options-rich so far. But: When I select a text with the mouse, it's not able to translate it, I have to paste it in the window. And when I select "mouseover translation to...". I get an error page. Please, fix it. And other problem: I see warning messages (yellow window) from Firefox about memory usage...
