The “AI translation” feature here has been on Firefox for years now. It was once an extension then just baked in to Firefox. So it was always enabled by default that automatically translates a site if it found a compatible language and it is on-device so doesn’t use the cloud. They just added the “AI” label recently I guess to appease a certain demographic. I guess there are other people who really relate AI to being bad. But guys, these have been ON firefox for a long time, just renamed as an AI feature.
