No. No upsides.
Again, what can an LLM possibly do to help? Summarize the page I'm already reading? I don't want a summary, that's dumb. People who think their time is so precious they have to optimize a five minute read into a ten cent API call and one minute read of possibly wrong output are just silly. You aren't "freeing up time", you are selling your reality.
Buy stuff for me? Why? Buying shit online is so easy most people do it on the toilet. I've bought things on the internet while blackout drunk. I also have a particular view of "Value" that no LLM will ever replicate, and not only do I have no interest in giving someone else access to my checkbook, I certainly do not want to give it to a third party who could make money off that relationship.
How would I no longer need browser extensions? You're saying the LLM would reliably block ads and that functionality will be managed by the single human being who has reliably done that for decades like uBlock origin? How will LLMs replace my gesture based navigation that all these hyper-productivity focused fools don't even seem to know exists? It certainly won't replace my corporate required password manager.

Come on, get over yourself.

So Mozilla, who isn't even allowed to spend $6 million on a CEO is somehow magically going to invent super AI that runs locally? Get a grip.
I also hate concept of summaries, as well as related concept of AI text inflation.
I'm also against any third party being involved here. I'm pointing out the potential of AI in the browser, but for me it has to be locally run or it is a no go.
My point is that browser plays a central role in our digital interactions. Extensions help with smoothing out the experience. LLMs could write those extensions, or serve as an agent to further make the online interactions more pleasant. I could see myself using it to either optimize my existing experience, or to vastly broaden the communication surface in directions that currently hold too much friction.
The rest was a joke, sorry if it made your day worse.
