Simple and the best so far...

The best app for me! Sometimes the app doesn't work, but I think it related with architecture of sites where I used the app. Thanks to this app I am study English. As you can see Grammar is my next goal, but vocabulary is good. Thank you so much Andy, good and usefull app!

The best! I tried almost every translation extensions. Don't waste time looking for another one. This is exactly what you need so far!

sometime does not show. reinstalling the addon fix the issue

Хрень какая-то, даже удалить из браузера не возможно!

EDIT: is there a daily limit for translations? After a long use, it doesn't work anymore.

It's one of the best translator addon now.
(When I installed it, it gaves me an error when translating. After a few moment, both, translation and TTS in all languages is working.) The auto detect language feature is great. The translation history is great. The arrow to switch target and source language is really useful too. I use the addon button that opens a popup.

Things to improve to make a super extension: When I select a text, it doesn't pass it automatically to the addon window. I wish it does.
Please, let me select only a few languages, the list is too long, and it's not easy to switch languages.
