Great, simpledictionary (though would really love more languages added, like Arabic). Besides the language limitations, my only quibble is one that has been mentioned: popups shouldn't occur in edit fields. Double clicking on a word to retype it brings up the popup and obscures the text.

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

works great

It used to be perfect, one day the dictionary stopped working and says no definition found.

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?

Continuously get the "no definition found", tried turning off all my other extensions but that wasn't it, seems to be a problem wit the extension itself? Reinstalling did not work.
