I am deeply disappointed with the DeepL browser extension for Mozilla Firefox due to the lack of Arabic language support. While Arabic is available on the DeepL website, it is frustratingly absent from the browser extension. This inconsistency hinders the usability and accessibility for a significant number of users who rely on Arabic translations. As a result, I am giving this extension a one-star rating. I urge DeepL to prioritize adding Arabic support to align the extension's capabilities with those of the website and better serve their diverse user base.
