Personally, I do not mind it if it's on-device, especially small specialised models (e.g. overview generation, audio generation, etc) with no internet access.

OneDeuxTriSeiGo

That was the original intent. They only recently added the "chatbot-y" kind of stuff since the infra is all already there. The main uses were for their translation tools and PDF alt-text generation (which I believe disabling ML will disable as they rely on the on-device transformer tools to do).

ASalazarMX

I disabled browser.ml.enable and local translation was still working. In my case, that's all I need, but it looks like it still allows on-device transformers.

In the long term, on-device won't save us from a biased assistant. It might notice we seem tired and insinuate that we could use Mococoa, all natural beans straight from the upper slopes of Mount Nicaragua.

Or—and this happens—it "summarizes" the same text differently, depending on whether the author's name happens to fit a certain ethnicity.

Modern local models make it pretty easy to imagine a future where this would be useful, but they also make extremely apparent that the future has not arrived.

Maybe in five years they will be useful enough that it would have been worth including these features

I've used Firefox for 15 years and I really don't want to use Chrome. Can Mozilla just, like, make a good browser?

SECProto

Not defending mozilla adding AI to firefox, but...

If you've tried chrome recently, you'll know that it's jam packed full with even more stuff you don't want. And the article lays out how to easily disable all AI in firefox (which you cant do at all in Chrome)

ASalazarMX

I'm very pleased that disabling browser.ml.enable doesn't disable local translation. I don't need a dedicated UI for chat bots, but I find local translation very useful.

I think they make a pretty good browser. It is performant, supports blocking ads easily, standard compatible, customizable and recently even added support for vertical tabs. What are you missing?

eviks

It's poorly customizable, you can't even change keyboard shortcuts (extensions can't do it globally either). Vivaldi is customizable.

PaulHoule

The ad blocker keeps it viable.

Personally (I’m not the person you asked) I’m missing AppleScript support. Firefox is the only major browser without it, and the bug report for it is old enough to drink in every country.

That lack of capability prevents it from being my daily driver, even if the rest were good enough (I’m not saying it isn’t, I’m saying I have no reason to find out).

I am certain I have inadvertently pushed many people away from Firefox for that reason alone, because when they ask for me to add Firefox support for my tools, I have to tell them it’s impossible.

I have tried to talk to Firefox developers about that a few times, at open-source conferences and such, but they think AppleScript is some power-user feature and fail (refuse?) to understand power users drive adoption and create tools that regular users rely on.

I remember whenever a Firefox story was submitted on HN, multiple people commented “I want to use Firefox but it’s missing <whatever>”. Then Mozilla started doing a lot of questionable stuff (all of which they eventually abandoned) outside their core competency and even pulling distasteful marketing stunts, and at some point people started commenting even that. I presume many got tired and gave up on Firefox entirely. I almost have. I now root for them only conceptually, because browser diversity is good.

I also noticed that no matter how politely someone pointed out on HN “Firefox doesn’t fit for me because of <whatever>”, they always got downvoted. If valid polite criticism is buried, no wonder things stay the way they are.

dingaling

MacOS, Linux, FreeBSD and everything else squeeze into just 15% of Firefox's user base.

https://data.firefox.com/dashboard/hardware

They're really not going to be able to dedicate resources to something as bijou as AppleScript.

yoavm

Interesting! The last time I used a Mac was many years ago, so I'm not sure what would you do with AppleScript in the browser. What are some example use cases?

tjpnz

I recently discovered that the sponsored sites on the homepage I had previously removed have reappeared. I've had similar issues with a few of the buttons on the browser chrome I had also removed. I'll still use it because I don't want to deal with the security and privacy nightmare that is ads. But it's a bit annoying to have to play this game of whack 'a mole.

array_key_first

Yes, because as we all know, Google would never shove AI or ads in your face.

I disagree with Mozilla here, too - but you can't cast Chrome as a magic spell. Chrome sucks ass. Google sucks ass. It's trivial to suck less ass than Google.

sdairs

Chrome does suck ass, hence why I use Firefox and said I don't want to use Chrome, lol. But I want Firefox to be a good browser in its own right, not just "not Chrome". Firefox is just about over the "acceptable" line for me, as a power user for 15+ years (and under that line for most normal users) so I continue to use it, but they're neglecting it in favor of these useless AI features.

Firefox focus

mingus88

I use focus daily, but it’s not a daily driver.

It doesn’t to tabs, and links that the site forces to open in a new tab often don’t work. It also doesn’t do JS well by design.

I use Firefox focus for throw away links I come across, but for everything else I need a full browser

Kwpolska

You can’t open a new tab yourself, but you can open it by long-pressing a link.

If you’re running in a Custom Tab on Android, you need to switch to the full Focus if multiple tabs are involved.

akomtu

Being good doesn't pay well these days. Being evil, on other hand, does.

braebo

Use Brave. It’s de-googled, privacy-centric chromium with built-in uBlock-style ad/tracker blocking. Best of both worlds!

presbyterian

There are some good reasons to consider not using Brave: https://www.spacebar.news/stop-using-brave-browser/

archerx

Still going to use Brave though.

bdangubic

this is from 2023 and is also mostly wrong on almost all accounts, basically FUD

protoster

De-googled Chromium? This does not compute.

hypeatei

De-googled in the "we make some patches to remove things we think are hostile from Google" sense but yes: they're still completely reliant on them for engine development.

grayhatter

Brave, The browser that brags about how they ignore consent!

sdairs

Yeah I'm not at all interested in Brave, that's a dumpster fire of it's own. And that still gives control to Google by owning the defacto implementation of browsing the internet. There needs to be an actual alternative to Chrome.

babypuncher

So much about Brave raises scammy red flags every time I look at it.

However, my main reason for ditching Chrome years ago was the fact that I think a browser engine monoculture is bad for the web as a whole, especially if that engine is primarily controlled by a single corporate entity.

Manifest v3 and other Google nonsense came later, and are extra reasons to stay away from Chrome, but I still feel strongly that a good alternative needs to use a different engine.

porphyra

Mozilla could have had the no-nonsense, high performance browser backend that everyone uses to build their own browsers (like the recent glut of AI browsers), instead of everyone using Chromium/Blink. In the past, Gecko was really the go-to choice for this. They almost had a second shot with Servo. But they kinda really dropped the ball on the technical capability of the browser while continuing to be distracted by all sorts of random gimmicks like Pocket and then this. Sad!

bitpush

> Mozilla could have had the no-nonsense, high performance browser backend that everyone uses to build their own browsers

I agree with the sentiment, but you underestimate the level of engineering, coordination, design work, testing it is to do this.

It is admirable that they even have a half-decent browser, but to compete at the top you need soooo much money and motivation.

rudedogg

I’m guessing Ladybird will prove you wrong in due time

wobfan

Ladybird will be a Firefox alternative, nothing more. It can't be, by definition. People are not using Chrome, Edge or Safari because they're great browsers. They use it because it's preinstalled and good enough. They don't care, and they won't care in a future where Ladybird is a thing.

Ask 60% of their (Chrome, Edge, Safari) userbase, and they won't even be able to tell you how their browser is called.

Barrin92

Modern web browsers are in the range of 30 million LOC, probably 50% of that is just pure implementation of web platform standards and engine work.

Do you just need to advertise stuff among content creators these days with common sense going out of the window? It'll take them a decade to catch up without any engineering funding at the level that Apple/Google/Mozilla have.

doublerabbit

> It is admirable that they even have a half-decent browser, but to compete at the top you need soooo much money and motivation.

Let's not forget the CEO who paid herself a $6.9m salary in 2022, $5.6m in 2023.

dontlaugh

Gecko was always hard to embed, which is why WebKit was developed by Apple and then widespread in open source projects.

mionhe

More accurately, why WebKit was forked from khtml by Apple.

dontlaugh

Sure. KHTML wasn’t embeddable outside KDE either until Apple made that happen.

SoKamil

The amount of money and research put into Chromium is nuts and it's borderline impossible to compete.

wvenable

Mozilla is a C-suite vanity organization disguised as software company. I love Firefox (I'm using it write this comment) and I really appreciate the developers who continue to work and improve it -- I just wish they were given far more resources to do it.

slig

I doubt the Mozilla C-suite even uses FF on their macbooks/iPhones.

blackhaz

We had Netscape Navigator which began bloating after version 3 eventually becoming Netscape Communicator with various sorts of useless bullshit. When it became so fat it couldn't even start without causing machines to swap, I remember Phoenix came out - a lightweight, fast Mozilla browser. It was a godsend, an immediate hit. I remember all my friends switching to it when it was, like version 0.x, because it was so much faster. A proper no-bullshit WWW experience. Then Phoenix became Firefird, then Firefox. Now Firefox is the new Netscape. Cycle continues.

ZenoArrow

Time to switch to Waterfox, it's basically Firefox with the privacy features that Firefox should have by default:

That doesn’t address the larger complaint your parent commenter is making that Mozilla dropped the ball on Firefox development.

Apart from the browser.ml.* config the newest update also adds and activates the @perplexity search shortcut.

Deleted it in my config. I'm solely relying on DuckDuckGo.

> I'm solely relying on DuckDuckGo

I've been fully on DDG for years but becoming slowly skeptical & looking for alternatives.

1. They're leaning heavily into "responsible AI", much like Mozilla

2. Might be just me but I feel like their algorithm became significantly worse recently. Over the years they've gone from being worse than Google in the early days to steadily improving & overtaking Google on quality (I made heavy use of !g until I started slowly realising it was no longer giving me better results). But now I feel like they've reversed & regressed again.

mikae1

https://startpage.com is a Google proxy instead of a Bing proxy (like DDG).

arcanemachiner

Pretty sure startpage sold out years ago...

roscas

Still, don't forget to install uBlock Origin on Firefox. If you don't have a Pi-hole, considerer installing one. If you use Windows (or android/ios/macos), there is no way MicroDollar won't know what you do or go, even if you have a VPN it still goes around the VPN. But if you use Linux, install OpenSnitch so you can control some other nasty connections.

username135

Can you elaborate on what you're talking about regarding microdollar? Or provide some more information about your claim?

The_President

Here's the link to the official archives of Firefox browser:

https://ftp.mozilla.org/pub/firefox/releases/

You're on your own running these in the wild; at least use a few other layers of security protection. Later versions of Firefox will not run unsigned addons unless you're running a development build, without running it from the debugger page. (Maybe someone can chime in with a workaround.)

flerchin

I like seeing new features in Firefox even though I won't use nearly any of them. It indicates new ideas and investment into software that I very much want to continue to exist, that I use everyday.

pr3dr49

If you want some DNS blocking without running pi-hole or AdGuatd, try something like https://mullvad.net/en/help/dns-over-https-and-dns-over-tls

I found family to do a decent job of not resolving ads and crapware. Other providers are available.

dotcoma

Disable AI, disable targeted ads... What's wrong with you, Firefox ?

LetsGetTechnicl

In their defense, they're in a bit of a precarious financial situation. Most of their money comes from Google, who happens to also be their largest competitor.

grayhatter

The amount of money comes from the number of people willing to use and tolerate their defaults. Surely, burning all the good will they've built up can't possibly improve that, can it?

interloxia

It looks like it should be possible to use a local model with a custom prompt.

Selecting text and having a action with a custom prompt/tool without needing a browser extension might be nice. It need not even be a llm.

I should figure out how to turn off ai in acrobat reader. It offers to summarize my sheet music every time I open it...

PaulHoule

Should be a bill of rights that you ask the chatbot how to disable it no it presents you a checkbox to permanently disable it and you click and you are done.

sgloutnikov

Was shocked last night seeing a quite annoying Acrobat Reader with AI commercial during the NBA game.

https://www.youtube.com/watch?v=5M1a7zY5iVM

jherdman

I'm curious to know what the AI does when it encounters sheet music. Does it do anything intelligible?

hyghjiyhu

It summarizes the lyrics iirc. There are ai programs specifically for sheet music and I actually use one that I'm happy with, play score 2.

dylan604

That would be funny. I'd venture most songs fall into "singer is really pissed after a break up" or "singer is really wanting to get some"

moritzwarhier

Just use non-enshittified software, for example SumatraPDF, unless you need some special Adobe stuff that it doesn't support?

smartbit

The Firefox Chat window doesn't allow running a LLM is a different container. At least I couldn't find a way, tried several plugins but failed. Now running my LLM of choice just like the author inside a pined & containerized tab.
