User reviews

Users appreciate the DeepL Firefox add-on for its accurate, context-sensitive translations and smooth integration with the browser. It stands out as superior to alternatives like Google Translate, with helpful features like synonym suggestions. Some users note the paid plan for full page translation is costly, and the interface lacks adaptability to dark mode, which affects comfort. Minor usability issues like scrolling glitches were mentioned. Overall, the add-on is highly regarded for quality and ease of use.

В последней версии Firefox 139.0.4 при включенном дополнении и использовании редактора HTML на сайте livejournal.com, при написании больших текстов, и после выделения какого то отрывка, каретка перескакивает на начало текста, скрывая выделение. Исправьте пожалуйста, жутко не удобно стало пользоваться.
