Just installed, works really smoothly by opening an overlay when a word is selected, and contains a brief explanation of the word (tried with English text). This is exactly what I needed. Kudos to the developers.

this is a time saver for me, makes learning a lot faster and encouraged.

works great

Very friendly

Muy buena

Works really well, but I have a few questions: Is this considered as free and open-sourced, and does it respect my privacy, in essence, does it record and view each website I visit for tracking?
