What translator are you using?

The option was "translate with google translate", like in the link below.

I have noticed that two of my translater add-ons are not working. Contact its support page.

Try:

• ImTranslator: https://addons.mozilla.org/firefox/addon/imtranslator/

This one uses Babelzilla instead of Google for translating phrases from a page, in case you need a second opinion: https://addons.mozilla.org/firefox/addon/translator/

Example screen shot attached.

Sometimes if you cross between different HTML structures it can't process the content and you need to translate in smaller segments. Otherwise, handy for small jobs. For whole pages, Google is still king.
