The Firefox browser now allows you to test a local translation function for websites. So it gets by without a cloud connection via Google Translate, for example, as is often popular. The basis is the Bergamot Project, which has also been funded by the EU. The local execution of the translation should of course serve data protection. All developments of the Bergamot Project are published open-source.
The developer Sören Hentzschel reports that local translations in Firefox have been silent for a long time. In the meantime, however, according to Hentzschel, things are getting going again. Support for additional languages has also been introduced: Bokmål (Norway), Bulgarian, Italian and Portuguese are now part of the game. Declared as beta, you can even add Icelandic, Nynorsk (Norway), Persian and Russian.
The new version of Firefox Translations is not only ready for Windows, Apple, Linux and macOS with x86 chips but now also for Apple Silicon, i.e. the newer Macs with ARM chips. Also new are features such as translating forms, highlighting potential translation errors with red lines, and the ability to automatically translate pages while browsing in a tab without manually activating the translation each time.
If you want to test Firefox Translations in the new version 1.1.2, you still need a Nightly version / Developer Edition of the Firefox browser. The settings xpinstall.signatures.required must also be set to false and extensions.experiments.enabled to true using the about:config trick. The firefox_translations.xpi file can then be installed via GitHub.
