I want to see the source, and I don't want to worry about future browser changes messing with my settings..

fair enough. I'll add that one fantastic use I've found for LLMs is quickly checking the source of a given addon (though obviously this is no replacement for a real audit or finely-grained permissions).

I'd be doing this type of thing a lot more if browsers didn't make it difficult to load unpacked addons (in which case I could be modifying things I didn't like on the fly).
