In the nightly builds of Firefox, on the basis of which the Firefox 21 release will be formed on November 120, the list of language models in the built-in machine translation system, enabled by default, starting with the release of Firefox 118, has been expanded. In addition to the initially available models for English, Bulgarian, Danish, German, French , Spanish, Polish, Italian and Portuguese languages; models for Russian, Ukrainian, Estonian, Finnish, Icelandic, Catalan, Norwegian, Persian, Czech and Hungarian languages are offered for testing.
The timing of the integration of additional languages into the stable branch has not been announced (models may be delivered separately from releases after reaching the required level of readiness). Firefox's built-in translation system, which performs translation on the user's local system without accessing external cloud services, is based on the open source Bergamot engine. The engine is a wrapper on top of the Marian machine translation framework, which uses a recurrent neural network (RNN) and transformer-based language models.
Among the changes in the nightly builds, you can additionally note a new button for quickly clearing the private browsing session, clicking on which will lead to closing all windows and tabs in private browsing mode, and deleting the cookies, history and data associated with them. In addition, the browser provides the ability to search all open tabs using the “%” prefix in the address bar, regardless of the active container.
