About this extension
NOTE: The features previously offered by this extension are now integrated into Firefox, eliminating the need for any additional installations.

Firefox Translations provides automated translation of web content. Unlike cloud-based alternatives, translation is done locally, on the client-side, so that the text being translated does not leave your machine.

It can be installed on Firefox for Android Nightly or Beta by following these steps.

Firefox Translations was developed with The Bergamot Project Consortium, coordinated by the University of Edinburgh with partners Charles University in Prague, the University of Sheffield, University of Tartu, and Mozilla. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 825303.
Developer comments
A CPU that supports SSE4.1 extensions is required for this addon to function properly. If it doesn't, an error will be displayed when the translation is being started.
