Most people don't even read or understand that pop-up. My girlfriend for example used Bing and Edge for a few years without realising it. She only learned about different browsers and search engines when she started a trainee program in a performance marketing firm and managing ad campaigns became her job.

While my personal preference is Firefox, i also have work to do, and most work sites will work perfectly with WebKit, and not so great with the Mozilla engine, so at my work PC i effectively had the choice between Chrome or Edge.

I ended up going with Edge with the reasoning that both Chrome and Edge probably report a boatload of telemetry back to the mothership, as well as Windows 11, so there was no reason to share that telemetry with both Microsoft and Google if i could just share with one.

On the plus side of things, Edge to me feels better. It's actually not half bad (privacy issues aside that exists in both Chrome and Edge).

Name one site, that works "not so great" with Firefox.

Chase.com does not work on Firefox.

Default setting disable all JS. With JS fully enabled. Still doesnt work.

Using ublock and privacy badger.

I will also say theres another browser that does not work. I believe it is mullwad

Happy FF user for about 10 years and I wouldn't change it even if I worked at chase

I refuse to use chrome and I use vivaldi, opera, brave , edge and mullvad as well. Each has a specific purpose.

But my only general browsing browser is FF.

I use ff/ublock and the chase site works fine for me.

Basically anything that relies on Microsoft SSO, which is pretty much everything "enterprise".

It "works", but requires far too much manual intervention, with frequent authentication popups, as opposed to just using Chrome/Edge and be done with it.

I'm not ruling out that some of it is due to service misconfiguration by the auth team and service teams, but configuration errors or not, the end user result is the same, Chrome or Edge simply offer the path of least resistance.

I'm using many commercial sites using Microsoft SSO. I don't think I've ever been aware of an issue with Firefox.

Name and shame I say.

I've almost never had an issue with Microsoft SSO in Firefox. Be that with corporate Azure AD or personal Microsoft accounts.

I have had an issue with Linux and Microsoft SSO. Though that was more down to IT policies in Azure AD than it was Microsoft SSO specifically.

The only time Firefox was an issue with Microsoft SSO was when I tried to buy Minecraft and something about the Xbox / Minecraft / MS SSO required Edge. But that was one instance out of hundreds of interactions with MS SSO

AzureAD doesn't work with Firefox on Linux if you need a yubikey or similar as a second factor.

At some point FF wasn't able to do the user verification under linux (ask for a pin). Even though that's been fixed now, azuread still throws an error.

Chromium on Linux works fine. I haven't tried FF on Windows.

Not my experience for what it’s worth.

Still nobody can actually link a single site which doesnt work in Firefox.

I have been using it nearly 20 years, and still never seen a site I couldnt use in Firefox. Please somebody prove me wrong so that I dont just think everyone that says this is just doing something wrong!

EDIT: Not sure why I am getting downvoted, am I lying? If someone posts a link that doesnt work on FF I would be happy to concede. But I have been asking this for decades and nobody has ever given me one.

Used to work fine on Firefox. But since a few months, behavior has been pretty wonky with blank pages. Works fine on Chromium.

Works fine here in Firefox for Android. Sorry to say, but you just got proven wrong.

The actual account pages? Can you go to the transfer page and fill in the form?

The public page works fine.

I've used Chase.com for decades with Firefox (on Linux and Windows)

About five-ten years ago, I saw a few problems, but creating a new Firefox profile fixed that.

And using it with multi-account containers is nice too.

Chase.com works fine on Firefox for Android.

Don't you guys love blanket statements?

I have zero problems with that site using Firefox on Linux, Android, or Windows.

Curiously, most complaints seem to be from Mac users, and not just for this site, leading me to believe that something different may be going on on MacOS builds or APIs that it has to use there.

I use Firefox only, and use it for work to open outlook apps as well. I'm on Linux. Last week though I was traveling so my setup was my wife's macbook, with Firefox. Outlook would hang at the password login, but it worked fine on Safari. No idea why. I tried multiple times, tried emptying my cache and deleting internwt files, nothing... Anyone else ever had this issue?

About 80% of the “for your consideration” sites I get links to each year in awards season don’t work on Firefox, they outright refuse to use anything but Chrome, Edge, or Safari. No doubt something to do with the fun stuff they do to visually watermark the stream such that they can prosecute my ass if I share it anywhere. My guess is loads of enterprise-internal websites also just refuse to support more than one blessed browser.

The only issue I've seen is, that some apps -- Proxmox, Jitsi Meet (via jitsi-openid) -- fail to authenticate against Keycloak. Sometimes. Sometimes clearing cookies helps; sometimes not.

But the weird thing is that this failure happens only on one computer (running MacOS). I have another, with synced settings & extensions & ublock settings (running Linux) and there it always works?

For a normal, public site, I've not seen any issue.

There are definitely a few javascript differences from Chrome and Firefox. Just look at the landing page for caniuse.com to see there are definite things that are not available in FF.

Indeed, take the "we care about your privacy/cookie" nags - the industry collectively decided it's still better for their bottom line to put these on every site, every time you visit in the hopes that you'd get fed up or click the wrong button.

I think most people are sleepwalking through life. They surely are gaining more than they lose. Just like the streaming services that have added advertising, or the car manufacturers who have climate control subscriptions.

Probably because for most people the important issues/choices in their life do not revolve around the choice of their OS, browser, streaming service, car brand, FOSS apps, etc. but around career, family, friends, kids, partying, traveling, having fun, etc. none of which depend on the choices of the former.

You might call this "sleepwalking through life", while other people will call it "just living life" and not worrying about the unimportant pieces.

Only HN tries to be an elitist stickler for these things which do not matter to 99% of people.

All the other techie sites are sticklers for - and this is true - bad behavior.

The reason is, techies live their lives more in browsers than other people. Just because most people don't, doesn't make it right.
