Firefox 4 now officially released

For those who wanted to wait for the official announcement from Mozilla, they have now added it to their download site.

As promised, Mozilla has released version 4.0 of its popular browser (on time) to its official download page after two Release Candidates found their way to testers earlier this month; And Mozilla will be hoping to top their previous Guinness World Record of 8,002,530 downloads within 24 hours for Firefox 3.0, which took place in June 2008 with parties in over 25 countries.

At the time of posting Firefox 4 had been downloaded 384,614 times according to the Mozilla download page, you can also view a map of those downloads (updated real time) here, which appears to show a different number, possibly from the official announcement from Mozilla at 7am PDT.

Based on the Gecko 2.0 engine, Firefox 4 sports an all new user interface, new ways to organize tabs, a revamped add-on manager, support for HTML5 video standards, multitouch support on Windows 7 and a range of performance and security enhancements.

Mozilla has indicated a desire to move to a faster release schedule following Firefox 4, with mozilla.org co-founder and Mozilla CTO Brendan Eich telling developers that users could be running the fifth version of Firefox just months after Firefox 4 is released.

We also have an extensive topic about Firefox 4 in our forums, as well as member submitted custom styles and tweaks for the browser here.

Using it on Windows 7 x64 SP1 and Ubuntu 10.10 x64.
FireFox Sync working perfectly between the two.

GTK integration theme needs a lot of work though, no where near as polished as the Windows version.

I've been generally skeptical of "alternate" browsers, and in the past I always liked IE's integration with Windows. With FF4, I'm impressed with a lot of features. I like the interface and in particular I was impressed with the way they implemented the quick switch in and out of "Private" browsing. The performance is fantastic (fastest browser I've ever seen), and I have yet to see a poorly-rendered page.

For the first time ever, I've made my default browser something other than IE.

Does anyone (on some forum sites) get the annoying option to leave or stay, everytime they reply to posts?? It happens on the MS forum, and its a PITA having to click on leave all the time. I dont know if its a "feature" in FF4, or the MS forum. It doesnt happen on the PCworld forum, or here

7 150 268+ downloads and counting... Amazing... Someone know how many times it was downloaded in the first 24 hours?

It's already over 9.5 Million, and in about an hour or two it will probably be 10 Million.
that is a lot of downloads

If you had firefox sync installed as a plugin , you actually need to remove it, as the functionality is built in now, and they conflict it seems.

not very easy on the memory this new release.i'm seeing more than 1.5gb of ram usage which in firefox 3.6 it gets to 600-800mb with only 10 tabs

I like it. Its faster and not much different for the menu for me from before as I was using Tiny Menu. Just take a little getting used to for a couple of things, but otherwise it is very nice.

I'm loving it but for some reason its performance on beauty of web demos is not very impressive but then again they are there to promote ie9...

Firefox borders on the sides in Windows 7 is very distracting when hovering over a link, it shifts up the colour gradient on the border because a bar at the bottom has to appear to show the URL. Hoping this gets fixed.

I really don't like blurry text in Firefox 4, I know I can get rid of it by disabling hardware acceleration.

There's the addon "anti-aliasing tuner", supposed to help, but frankly I ended by disabling hardware acceleration.

What I want to know is how to make the tabs smaller or as small as the ones in 3.6.* as they are a bit too big for my liking in terms of compactability if I have numerous tabs open at once.

There is probably a stylish script for it but I'm not an expert. But if you open enough tabs they decrease in size anyway ?

Only the width decreases in size not the height which is a bit larger than FF3. It fits less tabs in a row for me while using TMP ext for FF4 than it does with FF3.

The thing that annoys me is that you can't use the scroll wheel to scroll the bookmarks menu from the button on the adress bar, but you can scroll the one that becomes visible if you enable the menu bar.

Probably has my favorite UI among all the new browser versions.. shame it drags so much ass on my old PC or I'd switch. IE9 and Chrome run fastest on this old beast..

Tried it, didn't like it. Went back to 3.6...

If it's the interface you didn't like you can change it. I installed the moveable Firefox button addon and moved it to an unused toolbar to get rid of it, moved the tabs back below the address bar, turned the menu bar back on (which also reenables the title bar) and finally used the Stylish persona to get rid of the ugly glass effect. Looks very much like Firefox 3 now.

3.6 wont be able to support the new web standards, such as HTML5 and WebGL, which im sure ure aware of and thus you will either be forced to update or change the browser, because in 2 year u aint gonna be able to display a single page on the web, as all of them r gonna be using the new standards, that 3.6 _doesnt_support_

That's totally untrue, unless that particular website prefers to annihilate a good portion of their visitors.

how is THIS:

Browser Ver Score
Mozilla Firefox 3.6 155 (result of HTML5 test)
Mozilla Firefox 4.0 255 (result of HTML5 test)

"untrue"

firefox 4.1 or 5.0 will probablt have 355 score, then the ladder will go up - 355 out of 500, then firefox 6 will have 528 out of 800 ... and firefox 3.6 will have 2 out of 800...

3.6 has no hardware acceleration, besides that, you can make 4.0 look like that ugly old, outdated UI of 3.6, though it will just take up more space

you are being conservative right now, with each year PC stuff evolve at higher rates, as a PC thing, the web isnt any differnet, you can try using IE6 if you like, but it wont get you any further, you cant even watch youtube with IE6, same things will happen with 3.6 - the old veteran will slowly die, look at monthly browser usage statistics, and for specific versions of firefox, same as windows 7 vs windows xp, every month statistics show that XP is rapidly losing users who go to windows 7, same is going to happen with 3.6 users , they will go to the new thingie... so far there are ~3 mln downloads of firefox 4, no wonder if they reach 1 milliard .. sometime soon

3.6 IS ALREADY old enough to be used, still better than IE8... so like it or not, the prophecy i just made will be fulfilled, ff3.6 will die, you will be proven wrong ... even by the cockroach that stalks you every time you walk into the closet so... you cant do anything but to accept it, as its inevitable

I think he meant that you were wrong about every website switching to HTML5 and WebGL in 2 years. Look how long it took for sites to finally stop supporting IE6.

1.1 million according to the screen I just saw. I wonder if it shows the number of downloads based on what OS you are on (Linux here)

Loving it so far. Most of my addons worked. Mailcatch worked after editing the xpi. QuickJava is the only one I'm waiting on an update for. Text looks nice. As does the minimal UI (doesn't look as good on OS X though).

Only real annoyance was it wiped my pinned bookmarks from the jumplist.

What needed to be changed in the Mailcatch xpi?

Just the maxVersion in install.rdf to 4.0.*

This actually got QuickJava working too. But you have to turn on the add-on bar to see it.

They need to fix the smooth scrolling jerkiness and the damn fonts. Otherwise it's OK, I like that you make it look like FF3 if you like. It also works on older OS's as well, something Microsoft 'claimed' it could not do :rolleyes

Well the way IE works they're right, they can't. They could have written a somewhat crippled version for XP and 2000 like Mozilla did, but why do that when it's an outdated OS that you want people to stop using anyway?

Hmmm was running RC2 and then checked the About page and it looked like it already updated transparently. Very weird. Still downloading just to keep a local copy.

RC2 is the same exact build as the final. That's why it's called a release candidate.

So will users of 3.6.15 be offered an update?? Or will we have to go through a convoluted upgrade of installing this, importing our settings etc and uninstalling 3.6?

So all the moaning from the Mozilla team about not downloading FF4 before now was all over a stupid download record attempt? Cheesy.

It was more likely that they wanted to make sure all their mirrors were updated instead of a few million people hammering a single server into oblivion.

I kept reading so much about how chrome had surpassed Firefox, and people are switching left right and centre. I decided to use chrome exclusively for 1 month. At the end of the month, I went running back to Firefox. The 0.00196 milliseconds difference in a page loading in chrome vs. how well Firefox performs for me, and the addons that help make it great, just didn't make chrome worth it.

I really just didn't like chrome, at least not enough to replace FF, and I really didn't notice it being any faster, at least not on any scale that a human can perceive without the aid of some sort of computerized time tracking tool.

i kinda like it, i think everyone will agree that it is much much better than IE9, font rendering really sucks in IE9, FF4 is a little little slower than chrome, but still.... awesome, i'll be using chrome mostly but FF4 is always an alternative option!

loving this over ie 9 or chrome! cant wait for the next version too which should be 4.0.1 early april?

disregard, my posts are disappearing in IE9 for some reason and I thought they were being deleted or something. I'll file a bug report.

I don't really like it to be honest. I'd go into more detail but I did earlier and Neowin deleted my post.

That brings up some memories.. haven't used Veronica in a loooong time.

It's an old search/indexing type of protocol.. think of it as "World Wide Web version 0.5" of sorts.

Time to take this old dog out back and shoot it. Nobody needs Firefox anymore. If a site doesn't work with Chrome, you can use IE 9 (and vice-versa).

Over 300 million users worldwide seem to think differently. Firefox 4 will probably have more users on day one than Chrome and IE9 combined.

Speak for yourself. Personally, I'll stick with Firefox, where I've yet to find a site that just "doesn't work" requiring me to use another browser. I could say the same; nobody needs IE anymore, haven't used it since the Windows 2000 days, aside from the first 30 seconds after installing an OS to get another browser. Chrome? Over-hyped and over-rated. But that's just my opinion, which means absolutely jack to anyone else.

Too many people tend to forget that opinion != fact, or "it's good for me so it must be good for everyone" isn't a clear way to look at things.

Tell that to 500 million XP users ( more tham Win7 & Vista combined) + 150 million Mac users + millions of Linux users.

Not everybody else in the world likes the faster-as-hell-omg-1-ms-faster-in-loading-and-look-at-V8-bench-omg-so-high browser you praise.

+1 i totally agree.

its using 102MB without NOTHING loadad!!. what the hell?!. with 3.6 used 35MB and now this? without ANY noticeable change but that stupid icon at the top. Give me a break!

So you have things loaded then?

Nikos_GR said,
Still got that faulty (hanging) behaviour. It's a good looking-heavy-like-hell browser.

If you upgraded from 3.6 carrying on the same profile, it could be that.

After how many Betas?

I'd rather it be right than on time.

Remember that if you even know what a Beta is, you are NOT the general public.

After using all the latest browsers I think I'm going to stick with Seamonkey 2.1; same engine and html5 support as Firefox 4 but I like the interface better. IE9 is a very close second but it has issues with a lot of sites like ebay and the huge expanse of empty white space it puts in every listing.

I think I'll be using this for awhile. The fonts appear to be sharper on Neowin using Firefox than they do with Chrome. The scrolling and page zooming are also quite a bit smoother than they were with v3. On par with Chrome now. Love the new interface. Sharp and clean.

A much better interface than what I expected, a few add-ons are still not yet compatible, but, it's really worth the wait.

And the mobile version went to RC yesterday too, in the Android market. Posting this from it, not sure it'll replace the stock phone browser though. But Fx4 is default on the desktop for now.

Yeah for some reason it reset, it also reset the first time I loaded it this morning.

That number was taken from the official Mozilla site (at the time of posting).

Awesome, downloaded and it looks great, am sticking with chrome till I get some good speed and security updates from this , cheers

Firefox 4 feels dated already, it uses 2 X more space than IE to show the Tabs and Address bar and lets not mention the performance issues, and it still has that dedicated google search box ...

... What performance issues? Overall browsing experience feels the fastest/smoothest out of the bunch, Javascript benchmarks (on my system) put it literally a hair behind Chromium. Throw in the usual Firefox fangirl rhetoric and at least for me, it's a winner.

It takes 18 days to form a new habit. I say you'll still with Chrome even if Firefox becomes fast and more secure.

As for me, I'll upgrade to Firefox 4 after their 1st patch.

This is done on purpose as Mozilla cares about the privacy of users and does not wish that each key entry is send to some search provider.

http://www.imageupload.org/get...&n=fx4vsie9.jpg&i=1

i have compared how much each of them displays from a page when their UI is made as compact as possible

as you can see, the last sentences are completely displayed on Firefox, the same cant be said about IE, keeping in mind that both have their Favourites/Bookmarks tabs displayed, and IE tabs are in the same row as the address bar, and they still use a lot of space - there is one useless empty line of pure nothing in IE9 and you are still whining. ... ><

Agreed about IE9. It is utterly ridiculous how they don't use the entire title bar for anything! How did they think that it was okay to leave all that space and scrunch up the address bar and tabs in the same line?! How idiotic!

And personally, the Google search box is pretty unnecessary as well.

You can also hit customize and just drag it off. No need for Deviate to complain about something that is optional.
