This used to be called Definer and it was a better-than-perfect replacement for Google Dictionary. Recently dictionary, duckduckgo and Wikipedia tabs stopped working and when checking for comments or updates I see that they have changed the name to "AI Translator". I liked it better when it was the old thing that worked.

I was looking for something to replace google dictionary after moving from chrome to firefox. This extension offers the same functionality and much more as well. It's fast, easy to use, and very powerful.

Great extension!

A good solid alternative to Google Dictionary

the best translator extension on firefox, thanks

The PERFECTO. It just works like magic.

It's using a lot of CPU even when it's idle. Approximately around 60% CPU usage increases when I activate this addon.

Came here after dictionary everywhere or anywhere (whatever it was called) went down. Better if not perfect replacement.

It works fine in general, but on some websites, like Instagram, the bubble doesn't disappear unless I reload the page.

Works perfectly but you should read their privacy policy, just in case.

This is a new must-have for me. It's easy to use. Looks great. and all around incredible to have installed with your browser

Amazing addon, and very customizable. This is now a must have for me

everything you want from a pop-up dictionary

Works beautifully Thankyou.

Knows a lot more words then the competition and has more options to boot. 5 stars

It's good, but the main concern is that it lacks supervision from the Firefox team. I hope that will change soon.
