Why does Firefox get more errors than Chrome?

Aaah so you and your company were proponents of the "This Site is optimised for Internet Explorer"

Ok boomer.
- Woah such a scathing retort.
  Perhaps consider the accessibility angle why it's a bad idea only catering to one browser and that your team/company should do better than that.
  
  It was humorous. I try to take stuff lightly.
  Its not a bad idea. Nobody uses Firefox. We tested and there is no reason for us to start putting in the effort.
  
  Nobody uses Firefox
  well thanks to companies like yours, its not surprising that the trend is going downwards. Pfft who needs a vendor free Web after all, eh? Everything's Google now, yay!
  
  Trend is down, somebody just wrote it's up 🤣.
  Look, I don't care. I don't. I use what works and I develop for what works. Then I go home and spend time with my family.
  I have no interest of progressing any agenda for anyone. If mozzila what's to be a player, they should address the reasons why no one is using their browser. That for sure ain't me.
  
  I have no interest of progressing any agenda for anyone.
  except you and your company do and you are being ignorant of that.
  but hey, as long as it puts the meal on the table...
  
  Not ignorat at all. Very conscious about it all. I very consciously don't want to use a browser that breaks some websites and apps.
  
  it seems we are going in circles.
  You are willingly and consciously accepting the Web to be dominated by the biggest "do evil" ad firm called Google, do I get this right?
  
  You are going in circles, making a strawman for me. Chill. I'm not a soldier for any software. Use whatever you like. I dont care. I shared my experience with Firefox. I'm sorry it's different than yours, but it is what it is and no attacks on me and fallacies you what to string on are going to change it.
  It seemed like people were interested, so I answered all the questions, even those that were offensive and rude and many were (very nice "community" ). I think this is the end. Bye.
- I mean it's not a bad point, IE once had the market dominance that chrome does now. By all means continue only supporting one engine but at least be aware that you're gambling on the browser market not shifting again as it has done in the past.
  
  Look, its not like we wont notice a shift like that. It would be very easy to adapt if the situation warranted.
  
  If it were really that easy to adapt there would be no reason not to support Firefox in the first place...
  
  At that point its out of your hands. Once the users have fully decided only one browser is all they're going to use, because most websites only develop for that browser (gee sound familiar?) then whoever owns that browser owns the web. That's the point people are trying to get you to understand and you aren't getting.
  its not like we wont notice a shift like that. It would be very easy to adapt
  This has has happened before. It took over a decade to get people to start using other browsers. Your little company can't wave a magic wand and make the entire internet ecosystem shift, even though you were part of the cause.
  Firefox market share is going up. But because small vendors not testing on it, it's preventing its adoption. So you're letting Google own the web.
  
  That is a wild and completely wrong assertion. I'm not Microsoft. Im a guy that has used Firefox last year and the experience was sub par. So I switched back.
  I'm not letting anyone do anything. You are exaggerating to the absurd.
  
  Those were your words -- you said you would notice a shift like that and adapt, which to me is saying you think you could undo the harm once you noticed it. Maybe you worded it wrong.
  
  What harm? What are you taking about?
  If some miracle happened that all of a sudden Firefox would have a critical mass of users, we would start checking it. It's not a big deal.

If you're developing software for one client who only uses a specific browser, I can see this being okay, but several times I have chosen not to buy things from websites that were broken in Firefox. I don't bother to check whether they'd work in Chromium, I just buy it elsewhere.

The number of people who act like me probably isn't large in absolute terms, but how many customers have been lost because of a broken website that you didn't even know about because they just left without a trace?

This might not apply to you, but it's some food for thought whenever Web developers decide to be sloppy and not check compatibility for a browser that still has significant market share.

Same. I'm not bothering with broken web sites.
I'm not in the US though, so I don't get many of them.
The number of people who act like that is negligible. We tested for that.
We don't see it as that we are sloppy but that Firefox is not a good browser. We came to that conclusion because no other browser acts like that.
- Don't you think that it may be because Firefox is pretty much the only browser using a different engine that Chromium? There are literally two major browser engines, and you're developing for one them. Ofc everything else will act like Chromium, because they are Chromium for the most part.
  
  That's all really nice. But the fact is, we use what works. It's a pragmatic decision. They're are so few Firefox users and on the end issues are not very common.
  
  The number of Edge users is only a few % more, do you skip that too? Just check Chrome and Safari and call it a day?
  As someone that uses only Firefox and knows others who do, this really surprises me. If a website is broken on Firefox then it's shitty webdev work and I'll find another store.
  
  Edge is the same as Chrome, so no extra testing is needed for that.
  
  Yes, Edge has transitioned to using their own forked version of Chromium under the hood, but they make enough changes that it's necessary to test for. It's not like Cromite that takes Chromium and removes some things and change configs. They modify core components of the engine itself.
  
  Everything works fine in edge. Only Firefox has issues.
  Users don't care why that is. If their app doesn't work they won't use this niche browser that very few people use.
  
  Funny, we get more complaints about DuckDuckGo browser than anything else, and that's one of the few we don't test on. I know this because I make it a point to have someone from CS tell me about consistent pain points users are having. I wonder how many complaints about Firefox not working your customer service team is getting daily and you just don't hear about it because they've been told to tell users "just say Firefox isn't a supported browser and to try installing Chrome."
  You should ask someone in CS. Whichever agent bullshits the least (not the manager) - you might learn something.
  Almost 3/10 people accessing your sites are using Firefox. All those "images not loading right or whatever" are probably blatant to them, making them think "wow, what an absolute shit website."
  3 out of 10.
  
  Im grateful for you suggestions and your calls for me to learn something. I'm sure they are well meaning and not as patronising as they sound at first.
  The facts are : we don't get many Firefox users. As far as we know most things are functional if not 100% visually correct. We don't tell anyone not to use Firefox. I personally have stopped using Firefox because of broken apps (not mine specifically).
  I don't need to defend my position here. I don't care why apps are not working, they just aren't and I need them. Anyone can scream and cry how this is not firefoxes fault - nobody cares while the apps still aren't running.
- We don't see it as that we are sloppy but that Firefox is not a good browser. We came to that conclusion because no other browser acts like that.
  Your views seem to be very narrow despite being a developer.
  
  There are many misconceptions in your short sentence.
  
  I want you to point them out.
  
  That my view is narrow and that developers somehow can't have narrow views.
  
  That my view is narrow
  Yes. Your view is narrow. You do not care about the technical details and just label Firefox as "bad/broken" because you do not know how to work with it. That is a pretty narrow view. You do not care about the idealogical reasons that people bring up in here either.
  and that developers somehow can't have narrow views.
  I am expecting a person that is talented enough to be a developer to not have narrow views.
  
  That's a strawman. It is not like that at all and I never said it was. I even specifically said that I know the reason it is like it is. I do know how to work with it. And no, I have an ideology, something I mentioned many times : I'm a pragmatist.
  Many developers have narrow views. Probably most have.
- Funny enough this 'slop' is compliance, but hey you seem to think you're mega dev supreme so I'm sure you already knew that
  
  I never said anything about me. I only said I'm pragmatic.
- We tested for that
  Genuinely curious—how?

Ah. You pray at the altar of Google with the mantra: "It only works in Chrome or Edge. Why not upgrade your browser?"

What could possibly go wrong with giving all the power to one browser engine? If only there was a precedent to learn from...

Bruh, he just explained what his company's workflow is like. He wasn't espousing the opinions that everybody is accusing him of, just saying how his job requires him to work.
This community can be hyper-reactionary sometimes.
- Do you think that this workflow is some divine commandment? Developers like him create these. He should totally get some of the blame.
  
  Yeah I'm sure he, alone, is responsible for his company's practices, and isn't just a dude trying to make a paycheck.
  
  I never said he alone did it. I'm sure he'll be happy to share credit for any great product his company makes. Why not take some of the blame too? (I'm not sure if he does think that way though. He hasn't replied since. I'm just replying to other people.)
  
  Why should he take the blame for something he likely has no influence over? That's like blaming the Sandwich Artist because you don't like Subway's bread; he just makes the sandwiches, he doesn't design the recipe.
  
  Honestly, I'd be fine and understand that he cannot but be complicit in this due to powers beyond his reach. I'd eat my words if he says that he doesn't like it, but has to comply. But he seems like he's pretty happy with it. (Again, from that one comment.) I will blame the sandwich artist if he defends shitty sandwiches. Because one has to be responsible for their own work. They're free to not give a fuck about what anyone thinks. But they are complicit.
  
  I'm happy to reply. I don't think I'm complicit to anything else but an inconsequential business decision and I don't care one way or the other about it. I used to use Firefox, but I stopped because some apps were broken on Firefox. I'm not a soldier for any browser im a pragmatic user.
Haha, no. We don't pray. We make web apps to make money. Catering to a negligible users who for some reason want to use the single browser with issues, that's up to them.
- I use firefox exclusively, on both my laptop and my phone. It works perfectly on any website I throw at it. I work for a startup which makes video call apps, the web client works perfectly under Firefox, and there's a grand total of 2 devs working on it.
  All this to say that if I come across your website and it doesn't work under Firefox, AFAIC it's your website that has issues, not Firefox.
  As for the reason, you might be fine with a single megacorp dictating the way the web works, but for many of us who remember what it was like in the IE hegemony days it's a serious concern.
  
  Again, I'm not a soldier for any software. I don't care. It's a pragmatic business decision.
  
  I guess my point is, you should :)
  
  I would, if there wasn't for my personal experience of using Firefox, when I had to switch to other browsers for some websites I used.
  Its because of that, that when we decided to ignore Firefox, I wasn't against it.
  
  You do realize that you had the experience due to lazy developers such as yourself?
  
  At what point do you think it starts being the problem of the software?
  Because I think that happened a while ago.
  
  When it's the software that's actually faulty. As others have mentioned, Firefox usually sticks to the standards. You're just using some peculiarities of Chromium, which is why you might be having issues. Anyway, this actually seems irrelevant to your stance, since you care more about the market share. Which is fine, being profit driven and all. But then you shouldn't get annoyed when people like me call you lazy.
  
  I shared my experience and almost everything I got was attacks on me. Many of them very personal about what I am and who I am even though nobody here knows anything about me. People are really offended, like I said something bad about their mother. It's effin bizzare.
  I'm sorry your favourite browser is not so successful as you want. Really truly sorry, but you don't know anything about me, what I do and how lazy I am.
  
  It's a question of
  How much effort (man hours which ultimately translates to $$$) versus how much revenue lost (people not buying because of Firefox bugs)
  In my experience this depends on your specific application. Sometimes there are weird bugs or behavior where you have to really hunt down what's going on. Other times it's as simple as changing a few css lines or something.
  
  It's almost impossible to calculate revenue lost, but as much as we tried, it was 0 or almost 0.
  Again, we don't even check anymore.

It's funny, I am not a web developer, but have built my own page for indexing my photo galleries.

It uses a lot of CSS, and I gave up on developing for Chrome/Webkit just because it is less precise, I make it work in Firefox because then I know it works fine in Chrome.

Way more efficient.

Well no. It doesn't work like that. Unfortunately.
- It did for me...
  
  That's great for you. These issues are not that common really.
  
  They would be less common if you developed for Firefox

It's like making a .txt document with tables and ASCII art and then on my God other text editors use different fonts and the look breaks. Only the most popular, Windows Notepad is supported.

Web was supposed to be bulletproof, easy to archive and implement. If a webpage break because a browser is supporting 99% of super bloated web standards instead of 99.5% of Chrome, there is clearly something wrong.

My rule of thumb is, try to randomly remove some HTML tags and CSS declarations. If whole site break and is unusable because of one/two lines missing, this website is a hack exploiting browser monoculture.

Again, I'm not a soldier for any particular software. I'm a pragmatic user. I will use whatever works and will develop of whatever works.
Some apps and websites are broken on Firefox, that's why we don't use it and don't optimise for it. We don't care it's not the fault of Firefox. It's a pragmatic business decision that is practically inconsequential, because Firefox has so few users.

I work in web and app development company and we don’t check Firefox anymore, because it’s the only outlier and has not many users.

Fellow webdev here, You're absolutly correct.

I mostly use Firefox, so I develop on Firefox and check other browsers for issues. That way, I can make sure the app and websites I'm working on still work on Firefox.
