I have no idea how the extension works, and Im not talking about the extension. Im talking about browser use broadly, and most people are not using the extension, there are a thousand other solutions.
However, Anthropic is one of the only labs who does a decent job at making models that recognize prompt injection attempts (but not completely immune) however Im speaking about giving llms in general access to your browser broadly.
I just know through my own experiments that it is quite easy to prompt inject an llm operating a browser and get it to send secrets. Using the extension might be safer idk, Om not risking it.
Llms are a security nightmare when connected to the web.
I have a website where I experiment with this. Although Ive stopped baiting llms into doing reckless things.
