I have logged in to give five stars to this extension.

The inability to use the instant pop up window on selected text (that disappears when deselecting text) rather than clicking an icon and getting a popup window is the main reason I don't use Firefox for the majority of my internet use. I want to be able to click and go.

This addon is really great and over the top of my expectation!

этих расширений вагон и маленькая тележка, но оригинальный google translate он не может заменить никак.

I would give 5 stars If it is a popover instead of a separate window.

Nice & simple, I love it.

Good:
Getting translated results in a popup window after clicking a button near selected text is a good UI style.

Hassle:
It doesnt save window sizes or adapt to the translated text size.

It doesn't have an option to save the source language (such as Detect), which means more clicks to get a proper translation.

Bad:
In Private Firefox windows it uses any Google signin session from a non-Private window that you may have open - so, it violates the very reason for having a Private window.

Please someone answer me, how it possible to use like the screenshots that used by developer of this extension; can sb teach me to use it like that? (( I don't want to translate on a new tab and just want a pupop like chorome extension))

Was surprised that only 10K users are availing the benefit of this add-on.
There seem to be 2 options to translate text.
(a): click on the icon on the right side of the tool bar. This translates the whole page (simply converts all foreign text to native text without leaving the page) and the google translate option box appears on the top. From this option box one can simply go back to the 'original' text without leaving the page.
(b) : Select text and click on the popup small icon over the text to see the translation in a popup window. One can hear the pronunciation if needed. Very good extension

Finally an add on that translates as a pop-up instead of opening a new tab. ALSO: props on the options that are user-configurable!

pop-up doesn't appear

It would be nice to be able to disable this add-on on some sites. For example, on Duolingo I find the icon that covers the button very disturbing and I often accidentally click the wrong thing.
