Refuses to translate several normal things. Can't translate bigger chunks of text. And even if I cut it to pieces, translations lack in Context a lot (get the pun here?).

Always takes sweet initialization time, when it really shouldn't - let me paste the damn thing first and then I'll wait all you want! Overengineered monstrosity.

It is inconvenient that I have to press the field yet again after swapping languages. Tab key navigation is very poor. Preferences aren't integrated with browser, which leaves a bad aftertaste.

Um die Funktionen gut zu nutzen, benötigst du ein Premiumabo. Ohne Anmeldung bekommst du nur sehr wenig Text übersetzt. Nach der Registrierung ist die angezeigte Textmenge nur unwesentlich größer. Reservo saugt eine Menge Daten für wenig Gegenleistung.

J'essaie de traduire un texte allemand,rien n'y fait.

Я не смог настроить почти ничего - панель расширения вообще не реагирует ни клики.

Мне не понравилось дополнение - постоянно вылетают назойливые сообщения, да и дизайн оставляет желать лучшего.

Can not turn off upper banner on youtube. I press "register", "login" and "not now" button - NO REACTION. It just hangs there and use screen space.

Reverso difines both "emotionell" and "emotional" as adjectives, the English "emotional". Unless both German words can be used interchangeably, there should be examples of when to use which word.

Memory leaks, please fix them. I have a message from Firefox, in a yellow window, that one of the scripts of the extension slows down my browser. Needs more languages.

It makes a lot of terrible translations. Sometimes the writers of Reverso translations are apparently amusing themselves by writing joke translations. It badly needs for the translations to be checked by an independent person.
Also it needs a way to report a bad translation. The built in reporting feature didn't work for me.
And it gets very slow sometimes.
It actually works better to open another tab for a dictionary and type in words to look up.

When double click/highlighting a word no Context button appears (in setting it is well checked).

Firefox extension constantly switch translate settings to Rus->French. I DO NOT NEED FRENCH! Only ENG -> RUS and RUS -> ENG sometimes. Please add default language to the settings! This automatic switching is pissing me off!!!
