In my opinion, it is one of the best add-ons with google translator.
I will recommend this addon.

The best in the universe! Light, simple, do all I need. Pronunciation of the source text and translation in the target language. I was desperate at first because FF 57 moved it in "Legacy" section disabling it instead of updating to this version, and I didn't notice that in the FF repo was already present this version working again with FF 57. :-)
Love it! The best!

Perfect! Great performance!

Very simple, easy to use, just use ALT key to translate selected text, like a lot!!!
Hope you remove toolbar on popup, dont need that!

LEGJOBB! BEST! <3
Ha Chrome-ról jössz és translatort keresel ne válogass, próbáltam az összeset ami eddig (2017-11-14) kint volt és ez a leghatékonyabb. Egyszerű a beállítása, Angolról Magyarra fordító, de a nyelvek változtathatóak.

Thanks to Developers for the fast working! <3 Gj Firefox 57 <3

Easy to use ALT key to translate seleted text, with more convenient translation features.

Simply the best translate addons!. it's simple, fast and free, no stupid registration needed.

My favorite extension

It is excellent! Thank you!

Very handy addon. Must have for people who read a lot in foreign language.

This is SUPER useful

Thanks, really nice addon for a faster usage of G Translator.
On Firefox v56, it seems to work quite well.

Toolbar popup converts all capital letters to small letters after pressing Enter. Why? It is very ennoing.

Quick, clean and simple.

Top, compatible avec FF 57. Indispensable !

Well thought-out, accurate, beautiful.

This is my favorite translator addon. When I upgrade to firefox 57 I was so sad to see the old one not compatible, but I found this continuation and it works just like the old one!

I have tried with no luck to find the alternative for old-timer QTranslator for years which I used to love. Eventually I found this. Thank to Firefox developer who push my to revise my set of extentions...
I really hope Andy will continue to develope and support this weasome (awesome! awesome!!!) add-on. It's just must have for multi-lingual users.
Andy, thank you a billions!

Works fine in Firefox 57

After switching to 57, I was fed up with manually translating everything and no other webextension was quick and simple enough for me. Everything works as they were in old format. Thank you!

This is soo cool! Thank you! It's awesome!

I'm extremely happy my favourite extension became now Web-Extension. I only use 3 addons ( Google Translator, Foxy Gestures and Ublock Origin ) while 2 of these are Web-compatible. Only Ublock Origin is not yet.

By the way, I'm using Fx 55 beta 1 and Google Translator 0.54, but the bubble doesn't show up after I highlight a word. Currently in order to avoid this, I'm relying on an other combination ( Press Shift + Highlight ) to do the job. I'm pretty sure it will be fixed...

It's useful and has a very nice UI/UX.
