Firefox, after 20 years, once again has an advantage over the other browsers.

Let's hope for new generations to get tired of so many ads to finally ditch chrome.

Unfortunately, new generations seem to be completely fine with this. People in general, they're just so completely captured by the dark patterns that I get the impression they cannot even imagine a world without them.

I install uBlock Origin on every browser I come across. Everybody notices. The internet just feels better, somehow. People can't quite explain what changed, but they know.

It's funny. Over 20 years ago, I got people to switch to Firefox because of the AdBlock extension.

In case people don't know, Firefox was the first major browser to even have extensions.

Also, Firebug showed what was possible with developer tools. Inspecting elements or network requests or whatever else wasn't really a thing before that extension.

There is only XUL!

Long dead. Now there is no XUL, only (private user) data (that Mozilla sells for revenue)

Mozilla made the joke themselves, about Firefox. "There is no data, there is only XUL" was an official XUL catchphrase. But now there is no XUL, and Mozilla sells private user data, so it's reversed.

I wonder if new generations will just get better and better at visually blocking off ads when they read. So many layouts are so common that I read a lot of sites and have absolutely no idea what ads they're running because 30-odd years of browsing rendered HTML pages has trained my brain to block off and not process certain areas of the page.

I'm not an advertising apologist, just pointing out that I can remember what ads were on a freemium TV station I watched two nights ago and what ads were on a radio station I listened to this afternoon but I can't remember a single web ad since...I don't know when. This might be because the TV ads have audio and visual, and with radio my alternative at the moment was looking out the window of my car, but web ads just seem very easy to mentally filter.

uBlock Origin Lite works decently on Chrome so I doubt this will help migration to Firefox.
Andrex 15 hours ago||
Exactly. The difference between the two is not qualitatively different for 99% of users.

I noticed that UBO Lite doesn't cause the ad boxes to vanish like UBO does. You see this on the likes of the weather.com webpage.
culi 8 hours ago|||
Exactly. The Lite version is basically "hiding" ads rather than blocking. The MV2 version stops the requests themselves from being made which save your bandwidth and battery. The light version lacks those benefits

If only they focused on making Firefox the definitive good browser instead of a platform for their AI efforts.

Firefox will never convince people to leave chrome on philosophy alone. I detest Chrome with a passion and refuse to touch it with a ten-foot pole, but cannot in good faith recommend Firefox to anyone in today’s world. “It kinda works” is about as far a compliment you can give it.

cadamsdotcom 16 hours ago|||
"It kinda works" is factually incorrect.

I have used Firefox exclusively every day on macOS for the past year, several hours a day, and have not one single time had to open another browser. None of the customers of my B2B saas use Firefox. Not once have I needed to test in their browsers except quick smoke testing to prove to myself that the rendering and details are identical. All my other browsing is indistinguishable from before when I used Chrome, and from on mobile where I (tragically) am forced by Apple's monopoly to use Safari.

Do you have evidence to support your false claim?

jjav 16 hours ago||
Agreed, I can't understand where these experiences come from.

I only ever use Firefox, at work, at home, mobile. Since forever, as long as there has been a Firefox (and Mozilla before that, Netscape prior).

There was one time about 8-10 years ago that I encountered a site that didn't work in Firefox, was some weird proprietary training module at work.

So yes, I did encounter one site that didn't work in Firefox in the last ~20 years. One.

I genuinely wouldn't be surprised if it was Google astroturfing every single thread relating to FF. Yes, Mozilla isn't perfect and had some questionable decisions, but we're somehow okay with the worse option out of the two? Somehow, Mozilla's decisions are enough to never use FF, but Google's infinitely many horrible ones are acceptable for.... What reason?

> Somehow, Mozilla's decisions are enough to never use FF, but Google's infinitely many horrible ones are acceptable for.... What reason?

I think these people are real and predate AI. I think it comes down to a fundamental psychology in how the two browsers are marketed online. Firefox users would say "Firefox is better than Chrome." Chrome users would say "Chrome is good." Firefox is touted as a better browser on the principle of the freedom it gives its users, and paradoxically, that draws heavy scrutiny.

I don't think I am doing a Goomba fallacy here. People that claim to care about privacy and browser freedom will express disgust with Mozilla then, in the same breath, say they are opting into Chrome out of spite, which is 100x worse.

> say they are opting into Chrome out of spite, which is 100x worse.

That is what is frustrating, indeed.

Firefox is not perfect. Nothing is perfect. There have been changes in Firefox over the years that I don't like. (I'm still hurting from it moving the tabs to the top, so annoying.)

In a scale of 1 (100% user-hostile) to 10 (absolutely perfect user-centered browser), Firefox only scores a, let's say, eight.

But chrome scores a solid 2, so obviously I'm not going to use it, ever, no matter if Firefox makes the occasional mis-step.

What do you think doesn’t work on Firefox? Aside from Google products purposely crippled, everything works just fine in my experience. It’s fast and stable. If there’s a bunch of AI stuff in it, I’ve not seen it. Of course I believe it exists, I just don’t ever read popups anyways. To be fair, I probably use 5% of the browser’s capability (I imagine many are like me). I browse websites and I have UBO installed.

In the last few months, I've seen a huge upsurge of sites that simply won't work for me in Firefox.

Not sure if it's the FF + Linux combination. Should probably try with a fresh profile to confirm.

It sucks, but I'm in on FF all the way. If much of the web stops working for me, it just means I have more time on my hands!

Silhouette 16 hours ago|||
Anecdotally my own experience is consistent with this with the same platform+browser combination.

It appears that there are now significant numbers of sites - or at least noticeable parts or features of sites - that rely on Google-specific APIs and haven't been tested on other browsers.

However visiting those sites from Apple devices is often similarly frustrating. I'm not sure this is an anti-Firefox thing. It seems more of a not realising there are other browsers apart from Chromium-based ones thing.

deweywsu 15 hours ago||
I kinda wondered myself if this was some kind of coordinated effort to make Firefox not work. It wouldn't surprise me if it was later discovered that Google paid some Linux subsystem maintainer to slip in some nefarious code somewhere that altered the way Linux implements rendering specifications ever so slightly such that Firefox appeared broken. Just the conspiracy theorist in me.

Slack "huddles" (video chat) work on everything except Firefox+Linux. Haven't tried changing my user agent yet, only just got onto Slack for work.

You can change your UA and add Sec-CH-UA to match Chromium if you want to avoid the (non-ADA compliant) browser bias.

I daily Zen (Firefox under the hood) and the only thing that I consistently need to open other browsers for is direct USB support (mouse/keyboard drivers in the browser). Other than that, I don't remember when was the last time something wasn't working in Firefox.

1. Vivaldi supports uBlock Origin, if you consider Firefox a "major browser" then sure also Vivaldi and Brave are major browsers

2. while I use uBlock Origin on phone (Firefox) and desktop (Vivaldi), it's overrated, AdGuard works under MV3 AND unlike uBlock supports element picker, so if I was on browser not supporting uBO I would switch to AdGuard since I can't live without element picker

Vivaldi 8.1 still supports it (Chromium 150) as loaded unpacked extension.

Edit: and latest August 14, 2026 Chromium 152.0.7977.38 based Snapshot https://vivaldi.com/blog/desktop/address-field-calculator-an... has this in patch notes:

"[Extensions] Re-enable and extend Manifest V2 extension support for the time being (VB-130324)"

I wouldn't be sure this is a long term solution. Maintaining a this into perpetuity would probably take a lot of resources that Vivaldi team might not have.
yborg 11 hours ago|||
Unless upstream introduces breaking changes I don't see why not. Google was killing this functionality for policy reasons, not because changes to the renderer required it or something. And LLM analysis is going to make maintaining forks easier going forward.
rasz 11 hours ago|||
For all possible MV2 extensions this is unsustainable for a small company. Supporting just uBO used by tens of millions of people? pretty doable as it only relies on few hooks into C functions that arent going anywhere.

Do people not remember Firefox changing their terms of service last year and allowing them to sell your data to third parties? I don't get it did people forget?

I switched over to LibreWolf and other browsers like that then and never looked back.

culi 8 hours ago||
They rewrote the terms almost immediately after the backlash. They also claimed the original terms were written in response to the overly broad legal definitions of "data sales" under laws like the CCPA. Which tbh sounds reasonable

We all just either memory-holed it or convinced ourselves that it wasn't what it was. Easy to think you just misunderstood what they said, even though they were very explicit about it.

I'm not sure why you're being downvoted; you're right. Firefox the browser is an amazingly capable tool but I wish it was shepherded by an org that prioritized its users' interests (privacy, performance, etc.) instead of ramming AI, crypto or cute marketing campaigns that NOBODY wants into its flagship offering.
