DeepL 无论是翻译速度还是质量都是所有翻译服务中数一数二的，其某些方面甚至超过了 Google Translator ，但在使用不支持翻译或不支持英译中的浏览器（比如 Firefox ，虽然 Mozilla 在 Firefox 118.0 及以后的版本中加入了翻译功能，但其并不支持英译中）就会有障碍，遇到全文都是英文的时候 DeepL 只有升级为 Pro 用户才能翻译全文，但 DeepL 又不支持中国大陆的银行卡（Union Pay），所以如果 DeepL 官方能够改变这一现状，我相信，DeepL 将会吸引更多的中国用户（毕竟中国是个人口大国）。

The default Ctrl + Shift + Y in Firefox for Ubuntu is used to open downloads, so you have to set a different keyboard shortcut - this is the only drawback

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

Como hago para que la opcion de traducir una pagina me aparezca a demanda

My first review (1 star/5) :
This extension makes almost all text input fields (writing a review on Steam, using MachineTranslation.com and so on) unusable. For now, I've disabled it hoping that a fix will come out soon.

Changes of December 24, 2023
The developers were responsive to the problem that I encountered. After a few tests, everything seems to work fine. So I'm raising my rating from 1 to 4 stars. If all goes well, I hope to come back and give it a 5th.

Excellentes traductions de deepl. Mais un bug d'affichage dans les zones de texte des formulaires est très gênant (le texte s'affiche en double, un aplat du texte apparait empêchant d'accéder aux boutons du formulaire, etc.)

So this addon is a good one, but I need an option for dragging and fixing this pop-up window with translation, because in some moments when the text is long, it pops up at the bottom of the screen and there is a very small area for viewing the translation, which is not convenient at all.

Bien. Utilisé depuis peu, je constate que sa présence bug l'écrit de commentaire dans ebay.fr. Mais bon, faut juste penser à le désactiver en cas de dysfonctionnement et ça roule!

it's good, if only there was an option to directly translate the pages, but good job

Please add dark theme!

Great translations! I'd love to have deepl write in the extension for writing suggestions.

Еще немного доработать и возможно будет лучшим!

It gives a smooth UX. It would be even nicer to see 3 or 4 suggestions.
The first one isn't always the best match. At least for Hungarian.

The extension works very well, although the icon does not appear on some sites. Also, when accessing the settings menu of the plugin, I found it difficult to customise the key combination. Apart from these aspects, I found no major difficulties in using the add-on. I recommend everyone to make use of this tool for instant translations, without having to leave the browser.

Same bug: on sites where there is text input in the form (for example github), after entering text and scrolling down there is a ghost frame with text.

Overall, this add-on is great, though it has some room for improvement, here are some suggestions:
An option to display the translation pop-up immediately upon text selection.
The audio to help pronunciation is good, but the TTS engine could be better(it's using speech synthesis capabilities provided by the operating system)
An option for a more minimalistic layout for the dictionary to avoid excessive scrolling.

As other users reported, there is still text box ghosting on many sites. It is a pity that developers totally don't care about it.
