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.

Does not work on Fennec Release version.

The only aspect of this plug-in that has worked is opening Google Translate in a new tab (and not even importing the text to be translated).

love it, but it doesn't work for a quiet while now. I get the error : "NET Error: Cannot Access Google Translate!"Translate!"

Very handy. I like it !

perfect!
