Perfect, exactly what I needed. A double click>popup dictionary with support for many languages and that doesn't use web searching. I'm glad it exists.

Sorry, gentlemen, the extension doesn't work was my previous message. Now I understood why it didn't: I tried the extension on the wrong page-Firefox's devoted to the extension. On the other one it works as it should, only better--It provides more helpful information than I expected. I definitely will use the extension. Thank you very much, gentlemen.

Click Dictionary finds a good translation to Finnish, my mother language. Even a correct answer appears on screen for modes other than infinitive eg.comparative, plueral etc. Recommended.

Great and simple add-on. Thanks

I don't need to copy/paste to dictionary if I need to translate something anymore. Built-in translator is much better than Google's translator.
