I've noticed that a lot of new web apps that work on Chrome are simply not supported on Firefox.

Is Firefox really this far behind?

It's as if Mozilla is critically underfunded and unable to make substantial progress on Firefox

The last major Firefox update was on January 13.

Okay, a new release is expected in three days.

Firefox release history

This is the release history of Mozilla Firefox. == Mozilla Firefox timeline == == Current and future releases == === Current supported official releases === Firefox 31.4.0 ESR Firefox 35.0.1 === Current supported test releases === Firefox 36.0 Beta Firefox 37.0 Developer Edition Firefox 38.0 Nightly === Future official releases === Firefox 36.0 Firefox 37.0 Firefox 38.0 Firefox 39.0 Firefox 40.0 Firefox 41.0 === Future test releases === Firefox 37.0 Beta Firefox 38.0 Developer Edition Firefox 38.0 Beta Firefox 39.0 Developer Edition Firefox 39.0 Beta Firefox 40.0 Nightly Fir...

Firefox is about 2-3 years behind Chrome overall

E10s is stalled

Mozilla is grasping at straws at this point. I might have no choice but to switch.

@DragonLord No, it's really not. It's just that Chrome has a huge market share advantage, so there are many web apps coming out that are targeting Chrome and not Firefox, and blacklisting the Firefox user agent without any justified cause. Or maybe there's one little trivial feature that they think they absolutely must have that only Chrome supports, but FF will support in a couple weeks.

Or maybe it's that a lot of people tend to run old versions of Firefox (e.g. in enterprises, or with the Enterprise Stable Release series), whereas anyone running Chrome gets auto updated without even being prompted to update

so if you target Chrome you know that it'll work because no one in their right mind runs outdated Chrome, but if you target Firefox, they might be still running Firefox 3.6 or some ancient crap like that

and Chrome is more generally willing to incorporate bad things like DRM and proprietary plugins and patent-encumbered media codecs, whereas Firefox at least has a conscience and resists doing that somewhat (though as of now they do support patent-encumbered codecs and DRM, but it took a long time)

@BGM not too sure. Pre post is hard to troubleshoot. Remove and reseat everything?

BGM

@JourneymanGeek Could there be a jumper or something missing?

Journeyman Geek

Maybe but doubtful.

BGM

What can I do to test that the board is receiving power?

It's not something that can be repaired.

Oo

@BGM actually if its a vrm rather than a chip set....

But at this point we're talking a massive time/effort sink

Basically you could find out what chips they are, check on say mouser, and replace them

Bob

2:19 AM

@DragonLord Uh, no?

DragonLord

I'm still using Firefox primarily because it's a bit more powerful than Chrome (more features, tab groups, better plugin support, etc.)

I'm getting increasingly tempted to switch, though.

Bob

@DragonLord e10s was briefly put on the backburner for a couple years because they had more important things to focus on - with great results. FF is now far slimmer on memory usage than Chrome. They've recently restarted dev on e10s in the last half-year (and it's already made its way into default on Nightly).

Honestly, for the most part FF is stable enough that e10s wouldn't make a great deal of difference.

OMTC alreay helps with that.

End of the day, the biggest issue was addon and plugin compat, which is mostly resolved by the compat breaks in recent versions of FF with a new addon SDK

DragonLord

Crashes happen, but they're weeks apart in my experience

Bob

I have no idea where you pulled a "2-3 years behind" figure out of.

DragonLord

@Bob howtogeek.com/165264/…

Bob

2:23 AM

If you look at ES6, FF is far ahead of Chrome (granted, it's still all marked experimental)

> No Multi-Process Architecture

> CPUs are gaining more and more cores, becoming capable of doing more work in parallel.

Blatantly misleading.

There's this little thing called multiple threads

DragonLord

The typical consumer CPU has at least two cores and can concurrently handle at least four threads.

Bob

(Which, again, OMTC helps with a lot)

You don't need multiple processes and OOP tabs/sites to render on multiple threads.

DragonLord

Yes, Firefox is multithreaded, but it's still slower than Chrome.

Bob

Though, practically, they were tied down a bit due to the need for addon JS to execute on the same thread. That was an issue.

DragonLord

A busy script can tie up the entire browser.

Bob

2:25 AM

They've taken the compat-break steps now anyway.

My only current gripe with FF is the lack of a 64-bit build. But that won't be an issue for much longer.

Chrome... I have a whole list of random bullshit it throws at me.

Starting with broken font rendering since the initial release.

As a dev that has to target all three major browsers (and all of IE from 7 to 11 -_-), Chrome and FF are tied for special-cases we need to make.

Though with FF it's often just picking a different prefix or using a slightly different property.

With Chrome, it's screwing around with rendering, having to redraw charts, etc. ... heck, IE8 handles those cases better than Chrome.

Oh, there was that stupid filetype prediction too.

Oooh, look, there's this application/octet-stream with the name a.ext... it looks like a zip file! Better rename to a.zip proceeds to mangle the filename so the user can't load it properly

They seem to have fixed that at some point, actually... hm. Might have to remove that crappy workaround now.

Still, all browsers (IE11 included btw) are ahead in some ways and behind in others. That's just how this works.

Then again, it's also wrong to call non-standard features "ahead". Just different.

It could end up being dropped further down the line (see: Web SQL)

Just trying to clarify on authorative DNS servers.. a DNS server is authorative if it knows something that's a little more specific info on the next host. For example, my local computer wants the IP of my comp in the CS dept, mycomp.cs.wvwc.edu (provided publicly routable ) - a dns query would go to the authorative server for wvwc.edu, which would go to the authorative server of my department,

cs.wvwc.edu, and that would be the authorative server for my hostname... is this correct, although a bit complicated example?

DragonLord

8:34 PM

Out of curiosity: Will I ever find a use for a machine with more than 8 cores or 16 threads in a client environment?

I'm playing with the idea of building a dual-socket Xeon workstation using type EP processors.

Assume budget is unlimited.

Once again, this is in a client environment.

DragonLord

8:50 PM

Anyone?

Bob

@DragonLord As always, depends what you do.

There's no answer for everything.

Web browsing? Nope. Graphics editing? Probably nope. Watching videos? Nope. Editing videos? Nope. Playing video games? Probably nope.

Unless you have a specific need for it, the answer is probably no.

In fact, such a machine might perform worse than the equivalent enthusiast machine, wince you have to deal with shared memory, GPUs, etc.

DragonLord

For a high-end gaming machine, considering current hardware, I would actually prefer the i7-5930K because higher clocks matter more than core count.

Yes, you're right.

I was just considering some special-purpose machine for exceptionally compute-heavy workloads (read: Folding@home)

Bob

@DragonLord Well, the whole point of that kind of task is you'd get more out of the idle time of 3-4 home computers than a single high-power workstation.

If you wanted to donate all that power, sure.

If you want to actually use it yourself? Not so much.

Actually, I can't think of anything off the top of my head that would benefit significantly.

I mean, sure, some image and video processing algos will benefit. And maybe some specific physics-heavy games like ARMA 3.

DragonLord

The only valid use case I could think of is in a high-density server/datacenter environment.

That's what these Xeon processors are really for.

Q: Why does a Xeon processor cost much more than a similar Core i7 part?

I want to know why the price of a Xeon CPU and a similar Core i7 CPU is so different. The CPU clock is more or less the same. I want to know this because I want to have an understanding of what kind of CPU is more suitable for me. I do heavy mathematical computations and simulations which may t...

Bob

But unless you're doing something extreme, you probably won't notice the time for the first two (and GPU would probably do better for video), while the games are relatively specific and even then rarely make use of more than four cores.

DragonLord

9:03 PM

I think I already know the answer.

4

A: Why does a Xeon processor cost much more than a similar Core i7 part?

Different Uses and Environments Consumer-grade Core processors are designed for everyday desktop or gaming applications and are therefore optimized to operate at higher clock speeds. Most consumer applications cannot take advantage of more than a few processor cores and would benefit significan...

Bob

They develop those games to target typical consumer machines.

@DragonLord Yes, but you did specify client (assuming home) uses.

DragonLord

@Bob The expectation is that no normal consumer machine will have more than 4C/8T.

Bob

Exactly.

There's the possibility you'd run some expensive operation in the background, too.

Though, at that rate you might be better off getting a second machine - the cost of a Xeon CPU alone (let alone mobo and other parts) would be more than a full second consumer computer.

DragonLord

Probably better spent on a GPU array.

3-way SLI GTX 980 is much more effective for Folding@home.

There are very, very few applications in a client environment that could ever require more than 8C/16T anyway.

Bob

@DragonLord I honestly can't think of any over the top of my head.

Heck, for most people I can't even justify an i7 over an i5.

(Even me personally... the only reason I'd benefit from the former is because I tend to run VMs now and then.)

DragonLord

9:09 PM

On a system using a i7-5960X and three-way SLI GTX 980, you could run a CPU slot with 12 threads and three GPU slots, one for each of the three graphics cards.

At about $4,000, the cost of a machine of this sort is less than the cost of one Xeon 18-core processor.

Bob

@DragonLord The 18-cores are an extreme example, though.

More typical to see 6-core parts.

And even lower.

DragonLord

8-, 10-, and 12-core parts are pretty common in high-density datacenter environments, though.

Bob

And even with a Xeon E5-2680 V3 you're looking at $2k-$3k just for the CPU. Double that of the i7-5960X.

@DragonLord Most businesses wouldn't even have that.

Even in a business environment you're mostly hurting for RAM and I/O bandwidth and redundancy. Not raw CPU power.

DragonLord

@Bob It's about US$1,800. 12C/24T, 2.5 GHz.

Bob

@DragonLord shrug I'm quoting Aus prices.

Though now I see I picked the wrong part to compare :P

It really depends on your needs. Running AD? DNS servers? Database servers? You probably want anything, anything and more RAM/I/O respectively.

DragonLord

9:15 PM

@Bob The same holds for the vast majority of lighter consumer workloads. I/O bandwidth is what really matters, hence the move to SSDs.

Bob

An application server might want some more CPU power, but even then probably not that much unless you're really big or happen to be doing something particularly expensive.

@DragonLord I would say it's even more true for businesses.

A DB server eats RAM like there's no tomorrow.

DragonLord

@Bob My VPS is primarily CPU-bound (PHP is horrifically inefficient). There's a DB but it doesn't see very heavy use, only as needed for the blog.

Most of the waiting time a regular consumer experiences using a PC is due to inadequate I/O bandwidth.

Bob

@DragonLord Where's your VPS hosted? Because you're probably getting a single core's worth, if that.

DragonLord

Linode, 2GB plan.

Two CPU cores.

Bob

It scales to an extent - you might see benefit up to 2, maybe 4, cores.

DragonLord

9:18 PM

Contention is pretty low on these servers.

Bob

But above that? No, you'll likely end up finding bottlenecks elsewhere.

DragonLord

Web server loads of this sort scale linearly with CPU core count.

Bob

@DragonLord You're also right about PHP being inefficient :P

DragonLord

Keep in mind Apache runs a separate process for every client.

Nginx and other web servers are mostly the same.

Bob

Not necessarily the core itself (though some language "features" also make that unavoidable).

PHP sites (Wordpress in particular) tend to be... ah... messy.

Not well optimised.

@DragonLord ...no, that's not true.

DragonLord

9:20 PM

It's Serendipity, which requires Apache.

Bob

Nginx uses an event architecture.

That's also available with Apache (event MPM).

But you're probably on the prefork MPM, which is, frankly, shit and only useful for mod_php (which is also pretty nasty).

DragonLord

@Bob I thought it's threaded nonetheless and therefore scales linearly with compute performance.

@Bob Yes, I'm on prefork

Bob

@DragonLord It's threaded, yes, but not a separate process per client.

DragonLord

Currently configured for 32 processes max

Bob

And it reuses workers.

Far more efficient.

DragonLord

9:23 PM

In any case, there's really no reason for me to build a desktop around Xeon processors.

i7-4790K is plenty of compute for the vast majority of use cases.

Bob

I still don't max out my i7-2600 most of the time.

Actually, I can't remember the last time I maxed it out.

If/when I upgrade, it'll be for newer mobo features more than the CPU.

DragonLord

On my laptop (i7-4800MQ, 4C/8T, 2.7 GHz + Turbo), I do run into CPU bottlenecks on some games.

A faster-clocked CPU would help.

But it's not a huge issue.

No game I've played so far genuinely requires more than four threads.

Bob

Oh, I'm sure my CPU is bottlenecking on games.

But it's not significant enough to really affect me. It can always run faster, but that doesn't mean running faster is noticeable.

And even then it's single-threaded bottlenecks.

(Game I play: runs at 100-200 FPS. Could potentially reach or exceed 300 FPS with better CPU and GPU. Do I need it? No. Do I want it? ...not really, actually, I'd probably never notice.)

DragonLord

I have two desktops on my mind, one ultra-high-end system, one regular gaming system.

I was considering the Xeons for the ultra-high-end build but now I don't even see a good reason to pick the i7-5960X because benchmarks actually show worse results than on the i7-5930K.

Once again, most games are not designed to use more than 4C/8T.

DragonLord

9:40 PM

At least I can put that thought to rest.

There's just no reason to get a processor with more than 6 cores, now or in the future.
