It's great.

Sorry

No definition found.

It works great on some websites but inexplicably doesn't work on others, even though the extension says it "Can always read and change data on this website"

Doesn't give uption to check spelling

Es muy buena extesión, me gustaría que también tuviera un modo oscuro.

It stopped working for a while, and wouldn't be able to define the most common words (or could define them once and then stop working after). Fixed itself when I reinstalled the extension. Great add-on otherwise.
