This is great when you want to learn new words, I love it!

Good Extension!!

I was looking for something like Rikaikun for other languages and found this brilliant open-source extension. Really impressed at how clean, simple and fast it is - just double-click a word and you get a dictionary definition, translation, and other handy things. I can tell it's really going to help me a lot with language learning.

Small request: Wiktionary would be awesome as a built-in source! It was easy to add it as a custom source though, so that's really cool too.

Awesome!.

amazing

Really impressed with this extension. Clean, fast, and genuinely useful without getting in the way. The double-click lookup works smoothly, and the level of customisation is excellent — you can strip it right back or tweak it exactly how you want.

Tried a few alternatives and this is easily the best balance between functionality and simplicity. Once set up properly it just disappears into the background and does its job perfectly.

Highly recommended.

fantastic in terms of convenience & customizability

Hands down...the best extension I’ve ever used. The feature set is absolutely wild

Definer was a fantastic app, although my Custom Source for WordReference has stopped working and I haven't been able to figure out why. WordReference.com is a wonderful resource and really should be built into the extension.

This addon is the one I was looking for years for Firefox on Android ! Just select a word, a sentence or a whole paragraph, and click on the bubble to get the text translated. Very great job 👏👍

Perfect as needed with additional features.

5-star extension if the translation panel is added by clicking on the extension for manual translations with the "copy text" button attached.
Still the best extension I've tried so far.
