Looking back with fresh eyes, I definitely think I could’ve presented what I’m trying to say better.

On a purely technical play, you’re right that I’m drawing a distinction that may not hold up purely on technical grounds. Maybe the better framing is: I trust constrained, single purpose models with somewhat verifiable outputs (seeing text go in, translated text go out, compare its consistency) more than I trust general purpose models with broad access to my browsing context, regardless of whether they’re both neural networks under the hood.

WRT to the “scope”, maybe I have picked up the wrong end of the stick with what Mozilla are planning to do - but they’ve already picked all the low hanging fruit with AI integration with the features you’ve mentioned and the fact they seem to want to dig their heels in further, at least to me, signals that they want deeper integration? Although who knows, the post from the new CEO may also be a litmus test to see what the response to that post elicits, and then go from there.

I still don’t understand what you mean by “what they do with your data” - because it sounds like exfiltration fear mongering, whereas LLMs are a static series of weights. If you don’t explicitly call your “send_data_to_bad_actor” function with the user’s I/O, nothing can happen.

I disagree that it’s fear mongering. Have we not had numerous articles on HN about data exfiltration in recent memory? Why would an LLM that is in the drivers seat of a browser (not talking about current feature status in Firefox wrt to sanitised data being interacted with) not have the same pitfalls?

Seems as if we’d be 3 for 3 in the “agents rule of 2” in the context of the web and a browser?

Even if we weren’t talking about such malicious hypotheticals, hallucinations are a common occurrence as are CLI agents doing things it thinks best, sometimes to the detriment of the data it interacts with. I personally wouldn’t want my history being modified or deleted, same goes with passwords and the like.

It is a bit doomerist, I doubt it’ll have such broad permissions but it just doesn’t sit well which I suppose is the spirit of the article and the stance Waterfox takes.
