Tốt nhưng cần cải thiện thêm.
Ví dụ khi double click chọn từ boats - bên nghĩa tiếng Việt -VI là "thuyền" rất ngắn gọn, nhưng bên nghĩa tiếng Anh -EN rất chi tiết phát âm, loại từ là danh từ và động từ ( cài đặt ngôn ngữ chính là VI, sau đó là EN ).
Cảm ơn rất nhiều.

Only 4 Stars because there's no possibility to change size and color of this small bottom for translating. . i use a black Background in Firefox and this tiny small blue Bottom is really hard to find.

Was able to install and create 2 languages (english, german).

Issues: Popup text does not seem to work. Is there a setting to activate it? I would prefer the hover search rather than side panel.
Is there any option to add another language? or a relationship like "German - Spanish", so that the translation appears first?

So useful to translate! I love the IPA. But there's always the side panel, I'd like to use the popup window, but I don't know how. And I would like to add more language, than the 2 preconfigured language you can add to switch from one to the other one.

The only missing feature is to save words or expressions.

Nice add-on, but I want to have an option to turn off the context menu for it. My browser toolbox is buggy and I couldn't seem to get the CSS ID for it. What is the CSS ID for the context menu of this add-on? So that I can turn it of myself, thank you!
Edit: Nevermind, found it, "#_3b70ac6e-090b-4455-b0be-ab852255cfee__context_find_meaning"

This is good! I started using this after an older Wiktionary plugin whose name I forgot stopped working when Firefox stopped supporting XUL. With that older extension, you could right-click a highlighted word and click a menu option that gave you an on-page window showing the full Wiktionary page for that word. This plugin has a few other ways to trigger looking up words - a neat optional button that appears over highlighted words, a toolbar button you can click to look up the highlighted word, or a hotkey (CTRL-Q). The page that pops up is a modified and shortened Wiktionary page. If the highlighted word is not on Wiktionary, the add-on can still often find the correct translation by looking it up in some other source.

For me, there are only two things that make this a 4/5 instead of a 5/5. First, the modified Wiktionary page that this plugin displays is missing a few things, such as translations. Second, and most importantly, the hotkey is not editable in any obvious way, and in Firefox on macOS it is set to CMD-Q, which is also the system hotkey to close programs on macOS. The extension overrides the system hotkey, which means that you can no longer quit Firefox in the most convenient way with the extension enabled. (Oh yeah, and the plugin defaults to the Vietnamese Wiktionary version, but this is very easy to change. :) )

Good, i like it. But, when i using "Reader View" mode in Firefox, Quick Dictionary isn't work. Why?
