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 👏👍

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.

Just installed it and I'm blown away by how good it is. It's really comprehensive and doesn't slow down my computer. W for the devs.

It's every useful extension rolled into one.

very efficient, easy to use

Отсутствие паузы при прослушивании -это полный пиздец.

Does what it says and does it well. That is all.

This extension is priceless

Perfeito.
