It's 2023. Why are we still doing user agent detection? We're supposed to do feature detection. userAgent is deprecated. https://developer.mozilla.org/en-US/docs/Web/API/Navigator/u...

Does using `window.navigator.userAgent` still work? Does it still return the actual user-agent? Yes, and because it does, people will use it. You (or standards) bodies can scream from the top of the mountains that it's deprecated, but it won't matter, because if it's there, it will be used.

Then why is it FF nightly only?

It is a matter of configuration in their black box. I am using Librewolf and cannot login to Teams with that either. I have similar problem dropping links in Teams to URL's on my own server. MS blocks them, and I always have to tell people to copy the URL and paste it into a different browser such as Firefox.

On Android, with FF installed and using a Work profile for all the Microsoft bullshit, both Outlook and Teams won't let me click on links because "there's no compatible browser installed" :D

Looks like someone made a boo-boo it’s simply based on the user agent, w/e string matching they do is too strict they aren’t checking for actual JS/WebASM compatibility or anything like that. Chrome stable with a non standard user agent doesn’t work on via the windows live url but works through the O365 corporate one, same with Safari Mobile without any user agent modification. This to me looks like stupidity more th…

> Looks like someone made a boo-boo it’s simply based on the user agent, w/e string matching they do is too strict they aren’t checking for actual JS/WebASM compatibility or anything like that. Microsoft has repeatedly engaged in malicious anticompetitive behavior. Without any additional information, I therefore think it's rational to place a high prior probability on this being malicious anticompetitive behavior. Th…

Fururologist here, Librewolf and firefox nigthly is probably 0.01 porcentaje of users, is probably lore we don't test this we say it doesn't work use something we test it, yes they should say is your browser but the avrege client is old man who doesn't understand what they download and don't wat to use opera from 2000 more than this, is better say use some of this

Microsoft has a long and storied history of claiming superior business acumen when it suits their narrative, and then incompetence when that does. “We are the smartest developers in the world” I’m told used to be something you heard on campus, presumably during the recruiting process, and in the board room. But if the Justice department comes knocking, they turn into Steve Urkel. You can’t have it both ways, and they…

> Microsoft has a long and storied history of claiming superior business acumen when it suits their narrative, and then incompetence when that does. Not to say that they don't play dirty, but this isn't actually a contradiction. When you hire 100k workers, you're going to have the smartest developers in the world AND the Urkels. And odds are the smart developers aren't being put to work on the login page.

First of all, Urkel is actually a genius, so it doesn't fit.

Second, if you know you have better and worse programmers you either control the work of the latter or you don't ket them work at your entry.

Nobody sees the work of your smart programmers if nobody could login.

So either MS is a lot dumber than I thought or they just don't care because they no most people can't or don't want replace MS software.

Seems like a strange business decision to give up a a percentage of the market to the competition like that.

The percentage of the market that holds a strong opinion about a nondefault web browser with already minuscule (and consistently declining) market share, and will actively avoid you for not supporting it, almost definitely costs more to cater to then to ignore. (Testing time, engine specific bugs and code, etc.)

That small percentage will be extremely loyal to whichever services will cater to them though. A small percentage of users all choosing to use your service can still be quite a lot of users if there is no real competition in the segment.

do people do not remember Dr Dos ? if a coyote eats your cat, its probably not an accident. its more likely because it's a coyote and that's what coyotes do. it's in their nature.

As a counter point there is Hanlon's razor > Never attribute to malice that which is adequately explained by stupidity.

If the smart guy mainly is dumb when it suits him, then it's malice.

Nobody here commenting on the fact that Slack blocks Firefox as well for voice/video calls?

I'm not a regular Slack user, but when I tried the voice call option earlier this week first I got a notification that they were switching to some new style of video conferencing called "Huddles", and it gave me an option to choose between "huddles" and "classic" video calls, which was confusing to begin with. I choose the latter, but I got a compatibility error with my browser, advising me to use huddles instead (really, they couldn't detect that earlier?). Anyway, when I tried to 'huddle' my customer, it simple said my browser (Firefox on Linux) wasn't compatible, and that I must install Chrome to use the feature.

This is where I closed Slack and used my phone to make the call.

Sounds like Hanlon's razor: https://en.wikipedia.org/wiki/Hanlon%27s_razor

Only ince or twice maybe.

BTW how can we trust Hanlon? Maybe he tried to cover up is own malice.

How do you detect whether the user's browser has a slow implementation of an API without actually freezing the browser for 8 seconds?

Imagine being someone who made a simple mistake, and people on some weird internet forum with no identity verification said "Oh, that guy must be malicious!" and you lose your job. How would you feel? It's justified, if I understand the point you're trying to make, right? Which is worse? Edit: Not that I expect much from here, but since there are a number of child(ish) replies, I might as well clarify this for the re…

You do realize the "someone" in question is a mega corporation worth almost 2 TRILLION dollars with around 200K employees? One with a long history of anti-competitive behaviour and "mistakes"?

I've worked on contracts alongside MS employees and researchers in the past, and I've been pleasantly surprised.

Three decades of experience in the field, and unfortunately, I don't have quite the brooding disdain for Microsoft. Their stock has lined my pockets, their employees have treated my respectfully when we've worked together, their products do what they're advertised to do.

Something tells me you're under 40.
