I dare to say, that this web extension is even better than Chrome native translation, as it doesn't interfere with the website activity, while in Chrome, especially with filling pages, it may cause the processing error. This web extension while being excellent, is shown below lower-quality "recommended" extensions, and while having full Android support, it is not available to be installed on a standard Firefox Android browser, being available only to Firefox Nightly users by a complicated procedure of collection import. To Mozilla developers - please, consider adding this extension to both your questionable and biased "recommended" category and to the standard Firefox Mobile version as well.
