Yes, up to some extent.

Some Firefox features, like automated translation for web pages and “alt-text” suggestions when you upload images in your PDFs, tab grouping, are powered by artificial intelligence (AI) based on small language models downloaded to your device. These operate locally — web page content, PDFs, images and tab URLs stay on your device and are not sent to Mozilla’s servers or used for training purposes without your explicit consent.

That’s good to know! It’s interesting that Firefox is using AI while keeping everything local for privacy. I wonder if they’ll expand these features further or integrate a larger model in the future.
