This addon is really good, very useful. But every time I open the pop-up dictionary I get a strong glare in my face because the dark theme doesn't work, it only works when I search for a word and I'm redirected to the page via the add-on. So my only request is that you add a dark theme natively to the add-on, my eyes would thank you and I'd raise the rating to 5 stars.

a huge thanks man!

The best and most comprehensive dictionary extension I've ever used by far. Sometimes however the 'mouse-over-a-word-for-a-definitions-popup' function, will stop working and I need to restart my browser to fix it. Otherwise I love this extension. I am using a non-standard browser (LibreWolf, a fork of Firefox), so this could conceivably be the issue since I haven't tested if it happens in other browsers.

I finally found the best dictionary after trying so many. Simply a fantastic experience.

Would have loved a floating word meaning

One of the best if not the best dictionary extension! I'm impressed by the features it has. Kudos to its author. But I don't understand why it's so underrated here, not so much users and feedback. It deserves more!

It is a great add deserve 5 stars, but I was wandering if it could show 3 languages one time.

好用，感谢！

Great extension!

I think one function is missing for 5-stars: I want to easily turn it on and off. With a right click on the button or in the pop-up menu.

Thanks!

Very good UX and a wide range of supported dictionaries. One thing I hope the extension will support is the ability to change theme (light mode and fontsize of the popup).

Well done! This is exactly what I wanted.

It's a good add-on save for one thing.....it prevented me from updating to the latest version of Firefox until I removed the add-on!
It can be a five star once this is rectified.

This is the best pop-up dictionary app I've found yet! I love being able to customize what search engine I want a pop-up definition from. I just wish I didn't have to make two clicks to get a definition from the website I want though. It should have the option to be fully automatic with one click.

EDIT: I wonder if it's possible to add a button for this addon to the toolbar for the SSS addon?

This addon solves the need of using lookup on macos. Thank you @river young
