My experience with occasional use over the past four months or so is that newspapers, business documents, and other formal documents often appear to have essentially perfect translation, at least in terms of sounding plausable without understanding the language translated. For more casual stuff like twitter posts or song lyrics it makes plenty of obvious errors, although of course some of that stuff makes little sense as written. It seems to have different issues than Google Translate, although not much if any worse overall from my limited experience. It sounds like after Bergamot funding ended there were some communication issues and the Translate Locally group that was working with the Firefox Translate group stopped working together and now have their own extension, as mentioned in another comment: https://news.ycombinator.com/item?id=33795141 https://news.ycombinator.com/item?id=33795141 That one can be installed outside the browser and would likely give better performance, although I haven't tried that yet. The other interesting open source translation software I've seen is Apertium: https://github.com/apertium https://github.com/apertium I don't think they have a browser extension unfortunately but it is an entirely rule based translation rather than AI models. I haven't tried this one yet either but hope to soon. I did try their web interface a few times: https://www.apertium.org https://www.apertium.org
