I'd love to live in your world for a bit... I can't imagine any future where having AI in your browser is a net positive for any user. It sounds like an absolute dystopian privacy and security nightmare.
Imagine you have an AI button. When you click it, the locally running LLM gets a copy of the web site in the context window, and you get to ask it a prompt, e.g. "summarize this".
Imagine the browser asks you at some point, whether you want to hear about new features. The buttons offered to you are "FUCK OFF AND NEVER, EVER BOTHER ME AGAIN", "Please show me a summary once a month", "Show timely, non-modal notifications at appropriate times".
Imagine you choose the second option, and at some point, it offers you a feature described as follows: "On search engine result pages and social media sites, use a local LLM to identify headlines, classify them as clickbait-or-not, and for clickbait headlines, automatically fetch the article in an incognito session, and add a small overlay with a non-clickbait version of the title". Would you enable it?
Especially since we know very well that they won't be locally running LLMs, everyone's plan is to siphon your data to their "cloud hybrid AI" to feed into the surveillance models (for ad personalization, and for selling to scammers, law enforcement and anyone else).
I'd prefer to have entirely separate and completely controlled and fire-walled solutions for any useful LLM scenarios.
I'm also now imagining my GPU whirring into life and the accompanying sound of a jetplane getting ready for takeoff, as my battery suddenly starts draining visibly.
Local LLMs for are a pipe dream, the technology fundamentally requires far too much computation for any true intelligence to ever make sense with current computing technologies.
And whatever accelerator you try to put into it, you're not running Gemini3 or GPT-5.1 on your laptop, not in any reasonable time frame.
You dont need to run GPT5.1 to summerize a webpage. Models are small and specialized for different tasks.
And the examples being given of why you'd want AI in your browser are all general text comprehension and conversational discussions about that text, applied to whatever I may be browsing. It doesn't really get less specialized than that.
I'm happy to say that LLM usage will only actually become properly integrated into background work flow when we have performant local models.
People are trying to madly monetise cloud LLMs before the inevitable rise of local only LLMs severely diminishes the market.
You also don't need Gemini3 or GPT anything running locally.
I've got Nemo 3 running on an iGPU on a shitty laptop with SO-DIMM memory, and it's good enough for my tasks that I have no use for cloud models.
Similarly, Granite 4 based models are even smaller, just a couple of gigabytes and are capable of automation tasks, summarization, translation, research etc someone might want in a browser.
Both do chain of reasoning / "thinking", both are fast, and once NPU support lands in runtimes, they can be offloaded on to more efficient hardware.
They certainly aren't perfect, but at least in my experience, fuzzy accuracy / stochastic inaccuracy is good enough for some tasks.
An 8B Ollama model installed on a middle of the road MacBook can do this effortlessly today without whirring. In several years, it will probably be all laptops.
For example: I was browsing a Reddit thread a few hours ago and came upon a comment to the effect of "Bertrand Russell argued for a preemptive nuclear strike on the Soviets at the end of WWII." That seemed to conflict with my prior understanding of Bertrand Russell, to say the least. I figured the poster had confused Russell with von Neumann or Curtis LeMay or somebody, but I didn't want to blow off the comment entirely in case I'd missed something.
So I highlighted the comment, right-clicked, and selected "Explain this." Instead of having to spend several minutes or more going down various Google/Wikipedia rabbit holes in another tab or window, the sidebar immediately popped up with a more nuanced explanation of Russell's actual position (which was very poorly represented by the Reddit comment but not 100% out of line with it), complete with citations, along with further notes on how his views evolved over the next few years.
It goes without saying how useful this feature is when looking over a math-heavy paper. I sure wish it worked in Acrobat Reader. And I hope a bunch of ludds don't browbeat Mozilla into removing the feature or making it harder to use.
Why waste time and energy on the lying machine in the first place? Just yesterday I asked "PhD-level intelligence" for a well known quote from a famous person because I wasn't able to find it quickly in wikiquotes.
It fabricated three different quotes in a row, none of them right. One of them was supposedly from a book that doesn't really exist.
So I resorted to a google search and found what I needed in less time it took to fight that thing.
It cited its sources, which is certainly more than you've done.

In my experience this means that you typed a poorly-formed question into the free instant version of ChatGPT, got an answer worthy of the effort you put into it, and drew a sweeping conclusion that you will now stand by for the next 2-3 years until cognitive dissonance finally catches up with you. But now I'm the one who's making stuff up, I guess.
Judging by your tone and several assumptions based on nothing I see that you're fully converted. No reason to keep talking past each other.
I think we've all seen plenty of hallucinated sources, no argument there. Source hallucination wasn't a problem 2-3 years ago simply because LLMs couldn't cite their sources at all. It was a massive problem 1-2 years ago because it happened all the freaking time. It is a much smaller problem today. It still happens too often, especially with the weaker models.
I'm personally pretty annoyed that no local model (at least that I can run on my own hardware) is anywhere near as hallucination-resistant as the major non-free, non-local frontier models.
In my example, no, I didn't bother confirming the Russell sources in detail, other than to check that they (a) existed and (b) weren't completely irrelevant. I had other stuff to do and don't actually care that much. The comment just struck me as weird, and now I'm better informed thanks to Firefox's AI feature. My takeaway wasn't "Russell wanted to nuke the Russians," but rather "Russell's positions on pacifism and aggression were more nuanced than I thought. Remember to look into this further when/if it comes up again." Where's the harm in that?
Can you share what you asked, and what model you were using? I like to collect benchmark questions that show where progress is and is not happening. If your question actually elicited such a crappy response from a leading-edge reasoning model, it sounds like a good one. But if you really did just issue a throwaway prompt to a free/instant model, then trust me, you got a very wrong impression of where the state of the art really is. The free ChatGPT is inexcusably bad. It was still miscounting the r's in "Strawberry" as late as 5.1.
And here you get back to my original point: to get good (or at least better) AI, you need complex and huge models, that can't realistically run locally.
Plus, the latency on current APIs is often on the order of seconds, on top of whatever the page load time is. We know from decades [0] of research that users don't wait seconds.
well, 2/3 is admirable in this day and age.
They basically already have this feature: https://support.mozilla.org/en-US/kb/use-link-previews-firef...
Do we have to re-tread 3 years of big tech overreach, scams, user hostility in nearly every common program , questionable utility that is backed by hype more than results, and way its hoisting up the US economy's otherwise stagnant/weakening GDP?
I don't really have much new to add here. I've hated this "launch in alpha" mentality for nearly a decade. Calling 2022 "alpha" is already a huge stretch.
>When you click it, the locally running LLM gets a copy of the web site in the context window, and you get to ask it a prompt, e.g. "summarize this".
Why is this valuable? I spent my entire childhood reading, and my college years being able to research and navigate technical documents. I don't value auto-summarizations. Proper writing should be able to do this in its opening paragraphs.
>Imagine the browser asks you at some point, whether you want to hear about new features. The buttons offered to you are "FUCK OFF AND NEVER, EVER BOTHER ME AGAIN", "Please show me a summary once a month", "Show timely, non-modal notifications at appropriate times"
Yes, this is my "good enough" compromise that most applications are failing to perform. Let's hope for the best.

Would you enable it?
No, probably not. I don't trust the powers behind such tools to be able to identify what is "clickbait" for me. Grok shows that these are not impartial tools, and news is the last thing I want to outsource sentiment too without a lot of built trust.
meanwhile, trust has only corroded this decade.
That pretty much sums up the problem: an "AI" button is about as useful to me as a "do stuff" button, or one of those red "that was easy" buttons they sell at Home Depot. Google translate has offered machine translation for 20+ years that is more or less adequate to understand text written in a language I don't read. Fine, add a button to do that. Mediocre page summaries? That can live in some submenu. "Agentic" things like booking flights for an upcoming trip? I would never trust an "AI" button to do that.
Machine learning can be useful for well-defined, low-consequence tasks. If you think an LLM is a robot butler, you're fundamentally misunderstanding what you're dealing with.
sure, you can imagine Firefox integrating a locally-running LLM if you want.
but meanwhile, in the real world [0]:
> In the next three years, that means investing in AI that reflects the Mozilla Manifesto. It means diversifying revenue beyond search.
if they were going to implement your imagination of a local LLM, there's no reason they'd be talking about "revenue" from LLMs.
but with ChatGPT integrating ads, they absolutely can get revenue by directing users there, in the same way they get money for Google for putting Google's ads into Firefox users' eyeballs.
that's ultimately all this is. they're adding more ads to Firefox.

but.. why? I can read the website myself. That's why I'm on the website.
I've already hit that option before reading the other ones.
> "On search engine result pages and social media sites, use a local LLM to identify headlines, classify them as clickbait-or-not, and for clickbait headlines, automatically fetch the article in an incognito session, and add a small overlay with a non-clickbait version of the title"
Why would you bother fetching the clickbait at all? It's spam.
The main transformation I want out of a browser, the absolutely critical one, is the removal of advertising. I concede that AI might be decent at removing ads and all the overlay clutter that makes news sites unreadable; does anyone have the demo of "AI readability mode"? Crucially I do not want it changing any non-ad text found on the page.
Ideally the user interface for any tool I use should never change unless I actively prompt it to change, and the only notifications I should get would be from my friends and family contacting me or calendars/alarms that I set myself.
Specifically, the AI does not generate text for me to read. All it does is decide which parts of the text that already exists on the page to show me. (It is allowed to interact with the web page to get past any modal windows or gates.)
