AFAIK there isn't a translator for Firefox or one that I know of that work. You best option is to use Chrome that will do far better and has Google Support that it will work better for onsite translation if that's what your looking for. Also Addons is not a firefox forum user help that is up to whom makes that Addon if they make a Translator Addon to support and keep up to date for translations.

It says maked my mozilla firefox it even haves the firefox emblem on it and that means it is from firefox. I don't want to have too much browsers. I have 4 now.(firefox(normal stuff), firefox nightly got replaced by firefox beta(for extra add-ons for specific stuff), firefox focus(for small and fast stuff) and chrome beta(for website translation).) In the future firefox beta is gone because the extra add-ons is then also available for normal firefox. And i don't want to have chrome beta just to have for translating websites. It takes so much space in for having so much browsers.

Hi

That add-on is currently unavailable for Firefox for Android but we hope to include it very soon.

In the meantime, you may wish to use https://translate.google.com/ in Firefox for Android.

Thank you But there is no way to request for a specific language?
