Does not work in Firefox Quantum.

I agree it would be better if it opened a temporary pop-up rather than the web page but it mostly works as is, my problem is that although it shows the correct page it gives me the accept cookies window in Romanian -- Why? I'm in the U.S.

You can see any word easily. Take the word, right click and click 'Search Cambridge' menu. İt's useful.

sería mejor si funcionara con una ventana flotante y no abrir una pestaña nueva cada vez que quiera traducir

Hello in firefox before Quantum , I always could assing it a keyword "d" , but now in Quantum I can't do that.
The option for select and search by cambridge is a good , but i like use the url/search bar , How we could assing a keyword for this extension?

open new tab every time.

This app is very useful as Cambridge dictionary is notoriously the best.
It would be useful even more if the app worked with a pop-up
