Just tried testing it a simple TWO word review on this webpage, and a pop-up says (Can only translate first 1100 characters)
Um, I only had 2 words selected, and in options I had translate only selected text, otherwise whole page.
So first of all, this tells me this add-on is trying to translate whole page, even though I told it not to,
and secondly, it failed at doing the first simple test I threw at it.

haresva mi...

There are no hotkeys for translating a piece of text into a new Firefox!!!

No settings for hot keys. Firefox is the newest. MAC

Only short text marking, many characters(1100).

Translate selection not working

v: 57 is not good

Not work with firefox 57 mac

Doesn't work with Firefox update 57.. no matter how little text I select it gives error that I cannot choose more than 1100 characters. Old version worked perfectly.

Con la ultima actualizacion de Firefox ... el Translator no funciona ¡¡¡

The best translator to quit using the Google Chrome browser

Why removed funtion pop-up (button) translate???

Se elimino la practicidad de uso con esta actualizacion del 17/11/17

Ma vaffanculo va.

Hi sir! I used to like it very much but now, there is one more step before having a selection translated. Since I use this add-on several time when I read English text, an option would be appreciated so we could use it like the versions before: RIGHT-CLICK on a selection and click on TRANSLATE SELECTION. If I want to translate the page (witch is very rarely) I could click the title bar icon and make a choice. Thanks for reading.

Удобно, спасибо.

bien pratique

OMG, hot-keys not work.

This no longer works. Firefox updated yesterday and the Translator did as well to the most current version also. Neither the webpage nor the selection will translate. I read Dutch football websites and need to translate from Dutch to English. I guess I may have to go back to Chrome. Poor work by the developer.
