For context, the part where they talk about AI:

We are approaching the use of AI in Firefox -- which many, many of you have been asking about -- in the same way. We’re focused on giving you AI features that solve tangible problems, respect your privacy, and give you real choice.

We’re looking at how we can use local, on-device AI models -- i.e., more private -- to enhance your browsing experience further. One feature we’re starting with next quarter is AI-generated alt-text for images inserted into PDFs, which makes it more accessible to visually impaired users and people with learning disabilities.

I mean, this is not "slapping an LLM on top of the software and calling it AI", it's integrating it into the browser in usable ways.

One usage of a local model is the local translation feature which was ... kinda nice? Not having to go online to translate? Pretty cool right?

This is similar here with the alt text, seems like a force for good?

Feels like they're fulfilling what they said in the first paragraph of the quote.
