Ne fonctionne pas.
Don't work.
Firefox 140.0.3 (Build #2016099943), on a Fairphone 4 with Android 13 (TKQ1.230127.002)

Didn't work at all on my phone. When I tapped the extension icon, nothing happened.

Please update Google translate languages list. A lot of them need to be added.

Does not translate faz.net using Firefox for android 126.0.1 (Build #2016023311), hg-6c033deedc28+
GV: 126.0.1-20240526221752
AS: 126.0

Used to work decently; now I'm running the latest version of Firefox and clicking the Translate Now icon in my toolbar does nothing. No menus or pages with choices come up, nor can I see anything to do with it when I right/ctrl-click on a page. I've reported it as non-functional to Mozilla. Please pay attention to/fix your add-on.

Exactly what I wanted. Check the About, you can set the destination language.

Exelente

I had the same experience as the last reviewer. I think the latest version doesn't work with FF 52.8.1. I had used the earliest version 0.5.0 with no problem whatsoever.
Edit: Thanks to the developer for the prompt response. I should have mentioned that I'll change the rating to 5 stars if I see this or an earlier version working as usual.
Edit (as of April): Yes, the new v. 4.0.2 works perfectly. 5 stars. Thank you!
Edit: There is a minor bug, right-clicking "translate with Bing" opens up a blank Bing translate tab with no text. Have to copy and paste it to the tab.
