Mozilla launches Firefox 4

After needing to release a second Release Candidate just over a week ago, Mozilla has finally signed off on version 4.0 and made it available to the public ahead of the official launch date of March 22.

The Firefox website has yet to be updated, but we expect this will happen within the next 24 hours.

The final version of Firefox 4 was originally scheduled to ship in November 2010, but repeated delays saw the release schedule revised on more than one occasion.

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.

But for now, you can grab Firefox 4 at the links below; 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.

Firefox 4.0 for Windows
Firefox 4.0 for Linux (x86, x64)
Firefox 4.0 for Mac

I posted something about this release in the IOS 4.3 Article by mistake! Can a Moderator help me out by moving the post from there 2 here?

Downloaded and tried it. Haven't used any of the RCs. LOVE the new layout...looks really good in Windows 7. The font rendering looks a lot better than Chrome does to me. Those are my first impressions.

I've been a Firefox fan for years, but I gotta say this seems like molasses compared to IE9. If it wasn't for Firefox addons and extensions, Id switch to IE9 exclusively.

What's up with the font? Hurts my eyes. Finally configured it to look like FF3...I'm somewhat happy except for the font. =(

Or perhaps try adjusting the ClearType settings; probably won't "do it" for everyone of course. Made a few adjustments, and not only is FF4 looking damn good, but I think overall Win7 in general just looks a tick better now as well as far as text goes.

According to Dailytech, there should be a country flag present on the address bar, but there's no sign of it. Could it be, they were using an extension and forgot about it?

And indeed, the GPU D2D rendering looks odd on some websites, while being absolutely beautiful on others.
After an hour of playing around, i guess it's actually possible to get used to top tabs, D2D and statusbarless..

That's Flagfox.

Firefox + NoScript + Adblock Plus = Win.

Chrome / IE / Opera cant compete with this - i like the simplicity of chrome but the lack of these addons or similar for me is a deal breaker.

Chrome has adblock plus. You can use notscript which is the same as no script.

Jen Smith said,

Chrome's version of AdBlock is pretty bad compared to the FireFox version though.

Um, it uses the firefox filters. Chrome as both adblock and adblock plus. There is a difference. Works just as well too.

archer75 said,

There's more to AdBlock Plus than just downloading a filter.. any third-rate addon can get a list, and most browsers have some sort of functionality that can do that. Should actually look at both versions then compare. The other AdBlock is just "meh".

Don't take my word for it. Ask the guy who wrote the thing. "Adblock Plus/Firefox still remains significantly more advanced than Adblock Plus/Chrome" Wladimir Palant on the ABP forums, 2/27/11 citing bugs and limitations in Chrome.

Firefox still feels like a dog to me. Slower than Safari, IE9 and Chrome. At least that's how it feels. Not to mention Chrome is more secure.

what OS are you using? Firefox 4 slower than safari? if you have old install of previous versions of Firefox 4 try doing a complete clean install of FF 4 and try again. and second make sure all your plugins are up to date.

Windows 7 as well as OSX 10.6.6 on my hackintosh. Firefox has been slower for a couple of years now. In fact I just did a clean install of windows on a new hard drive a couple of days ago and only today put firefox on it. So that's as clean as it gets. Firefox still lags behind.

It's about ****ing time! This had better be worth the hype, or else... I'll go back to Chrome. If anything, though, it'll be my "backup browser", just in case I come across a site that crashes (usually Flash-heavy).

Also less of a headache. Firefox stutters while scrolling which gives me a headache after a while.

In Terms of overall customization, chrome still doesn't cut it.

I'll wait a few weeks, if for anything else, to see if a bug pops up, but mostly to give the guys who program the 12 add ons, time to get them working on 4.x

Can anything be done with the text/font rendering while using hardware acceleration? There is some sites that scrolling is very sluggish on if hardware acceleration isn't enabled, so i would really like to keep it, but again fonts/text at some sites seems to have a bit of trouble with it.

Have you installed Windows 7 SP1?

Nitrius said,

Yup, i have.

Check windows update... i think there is some optional update for hardware acceleration issue making windows etc sluggish. (not sure if this will help but it's worth a shot)

also probably would not be a bad idea to make sure your video card drivers are fairly new also.

Hardware acceleration isn't making anything sluggish here, without hardware acceleration some sites have laggy scrolling, this is some kind of firefox issue, but hardware acceleration fixes this. On the other side, with hardware acceleration on the font rendering isn't really all that good, or its bareable, but its much better without.

And all drivers are up to date here, also all updates from windows updates is downloaded, so this is some kind of problem with Firefox and/or Windows or a combination of both, or maybe my AMD/ATI card is the problem.

Was hoping there maybe was a quick fix for it, but doesn't look to good atm, been doing some searching and haven't found anything useful yet.

One of the comments at Mozilla mailing-list suggests to calibrate the screen.

In what way? My screen is already calibrated how i want it, though i don't have any hardware to calibrate it with so it's not 100%.

Edit: If its ClearType, well i have run through that as well.

Not bad Mozilla. The smooth scrolling have improved a lot. Almost as good as Opera. Looks like this will replace Chrome as my secondary browser.

the best overall browser out there in the real world (i been using Firefox 4 since BETA 7)

Chrome is overrated if you ask me (no offense to Chrome fans). because on paper it's pretty much the best but in real world i think Firefox 4 is overall smoother feeling.

but when it comes to hardware acceleration in the real world i don't think anyone could go against IE9 as that's 'noticeably' better than Firefox or Chrome on my PC in measurable FPS.

Only for Mac and Linux. The Windows 64-bit version will ship with Firefox 5, according to the latest roadmaps.

sava700 said,

stay with 32 bits version, 64 bits version its not worth it just like ie9 it runs slower than 32 bits and have more issues

Worked on two of my machines on different networks. Maybe a regional or language thing.

UK / en-GB for myself.

I have been using Chrome for a while now. Never really played with the beta's/rc's of this. I am going to try it for a little bit and see if I stick with it. Liking it so far.

Looks like I'll still be stuck using a nightly build of some sort because I won't want to switch back to a 32-bit build on my Win7-x64 computer. I was hoping that when FF4 hit final they would include the x64 version too, but it looks like I'll be waiting for some sort of Firefox 4.1 release for that.

A 64bits browser is the ugly duckling of the technology. May be it (64bit browser) will turn in a pretty swam but right now is ugly, it is flooded with troubles, compatibility issues and (the worst) degraded performance.

thats right, from plugins compatibility to low performance. A 64 bits browser its not ready for prime time yet not in windows, linux or any platform, it seems the web its not ready for it.

Having tested minefield x64 and ie9 64bit for windows, opera, chrome and firefox 64 bits on linux, all its slower than 32 bits version.

In what situation would your browser need more than 4GB of RAM anyway though? I think 64 bit browsers haven't taken off yet because there's really no point in them.

same here basicly and there is a 64bit version of firefox but its not official.

but its 2011 bow NOT 2001 64bit cpu's have been around long enough now
with no native 64bit support from Mozilla they should be embarrased !

Not to split hairs too thin, but Mozilla does make official x64 versions of Firefox 4, they just happen to be nightly builds instead of a full release.

I'm sure the code is ugly in the x64 versions, and there really isn't any compelling reason to push the x64 version. I just simply want x64 versions of the apps I use daily because that's the operating system I'm running.

Staying with Chrome, restart the browser and things get done.. lol

Google, proving the efficacy of Chrome's built-in Flash Player and its early, insider access to Adobe's developer builds, has fixed the zero-day vulnerability that emerged last week.

The hole will be plugged on other platforms and browsers by a new version of Flash 10.1 and 10.2 that should've been released by now.

Actually, that's a good reason not to use Google Chrome... Also, Google proves nothing. Adobe made it possible and who knows why ( maybe rhetoric question ) ?

I don't like at all these tactics... Why adobe ignoring all others?

you do know 10.2 is already available for other browsers, right?
in fact if it were plugged "last week" thats late.

You are wrong. As usual there is a new zero-day security hole in flash. Only on Chrome it was fix the day after the annoucement. The rest of the world is still waiting (10 days after) for a fix.

Yeah, it may end up with a new version such as 10.2.xxnew and 10.1.xxnew, because they would eventually run out of numbers at the rate they drop the ball.

3. go tell google to get out of bed with adobe

I can't deal with chrome, not only does it have a service that starts up when you install it but two non browser processes running at all times even when your not using chrome. Even after an uninstall there are still updater service and processes still running. Chrome should not need any non browser services running at startup and at the least it should clean up this crap when you uninstall chrome.

I wont use chrome again until they make it a stand alone browser with no dependencies on services and startup processes.

Not a fan of Chrome either for many reasons, but might want to give Chromium a spin. Same browser sans a few Google specific items, including the updater service. Never much understood forcing an updater service for one application either. Chrome's not the first or the last to do this unfortunately.

Where can I get the installer for chronium? Looked on there site and it looks more like a dev site than anything, I could not find just the plain windows installer for chronium.

As far as I know there isn't one, someone correct me if I'm wrong. (I rarely use it, never bothered/cared to find out.) As I understand it, this is where the primary work is done, then Google takes a snapshot of it, adds their own stuff and releases it as Chrome. You either build it from source, or grab one of the nightly pre-built binaries.

I've been using it since Beta 2. I am glad to see it finally finalized. What a change from Firefox 3.

Indeed. FF4 has become so familiar to me now that 3 looks like alien technology. Back when the OS X rendering issue was unsolved I went back for a bit and hated it. There's just so much about FF4 that's better now.

Plus, when you've used the browser from the beginning, you can really appreciate all the work that's actually gone into it.

I've only had that with switching to Private browsing, then closing the browser and opening it back up (which is no longer in private browsing mode). It's like that with previous versions too.

Then it's time to update that 1992 POS. I installed this on my laptop I've had for over two years, and it's great. Very smooth and responds well. My ONLY complaint so far, is not being able to remove the 'Tasks' portion of it from the Star Menu bar. You know in Windows 7, where you Pin to Start menu, and it has an > pointing out showing recently opened items for that program? Yeah, there are three in there you can't get rid of.

I'm sure Mozilla asked you before to not post direct links to the releases folder, so they can do load balancing properly.

Yes, they did. Shame on Neowin.

TRC said,
Yes, they did. Shame on Neowin.

I guess it works two ways. Mozilla shouldn't put something in a publicly accessible location if they don't want lots of people downloading from there. Firefox has a lot of users keen to upgrade and they know that.

That said, if Mozilla has asked Neowin to not post direct links then perhaps it may have been a good idea to wait until the release is officially launched.

Regardless though, Mozilla made it available from a publicly accessible URL so what else do they expect?

I believed they asked not to post direct links to the releases folder on the ftp site ftp:// but on the http:// is is fine.

coch said,

Yeah, that was right. Disregard my post.

I started using RC1. I missed some features when I switched to Chrome. Chrome though is pretty damned quick.
Mozilla is right though, the long development times make the browser lack features that Google are churning out with Chrome. Microsoft have the same issue with IE but look to be set to resolve that with the release of IE9 and better support of recent standards. Mozilla should have released FF4 before IE9 though as the people who always hated IE are now actively using IE9.

Mozilla often releases release candidates as final if they pass all tests and they are happy with it. This is why you don't see the RC1 or RC2 in the about dialog. If they declare it final, then it is final and they will not compile a new version.

This is NOT Firefox 4 Final!!

Download this one, and then get the RC 2. Both digitally signed at the same time and have identical hashes. This is RC 2!

There is still a difference between RC and Final. If there weren't, we would have been saying RC1 was the final.

Personally, if I go to Mozilla's homepage and 4.0 is not plastered across the page, then it is not a final build and not officially released.

They obviously found something in the RC that needed changing, so they released RC2 found everything to be adequate for release therefore it gets pushed up to the final version.

I'm pretty sure that if there was a "final" it would be, as I said, plastered across their page.

For all anyone knows, there could be an RC3 after this one - that's my point, it's not final.

So it's in the /releases/ folder and not /rc2/ or /rc3/ because it's a release candidate? Don't think so somehow.

Maybe I'm looking in a different place, but their FTP site has both "4.0rc2" and "4.0" in the same releases folder. So I don't follow your argument.
http://releases.mozilla.org/pu...zilla.org/firefox/releases/

Again, my concern still stands that there is not a peep on Mozilla's own site. This means either this is not an official "final" or Mozilla is pretty incompetent in updating their site.

Most likely because the release is tomorrow and they want to break their previous downloads record.

last rc = final version

Personally, if I go to Mozilla's homepage and 4.0 is not plastered across the page, then it is not a final build and not officially released.

yea i agree... ill wait till their webpage updates with 4.0 everywhere and not givin u the option of 3.6 etc

apowers said,

That is completely false.

I don't think you understand release candidates then. They are, well, candidates for release. If that exact build has no problems found with it, it is called final, with no changes made to it at all. That's the whole purpose of a release candidate, and that's why developers use it.

I do remember Mozilla saying they put the final up a few days before it goes on their homepage to help relieve some of the bandwidth pressure when they do put it up on the main site

Frankly, I just find it funny that you are hen-pecking each other to death over this. It gets released the very next day. Boo-hoo, so someone downloads it a day early. It's a day. A DAY. You want to fight over Release Candidates.

Isn't that the point of a release CANDIDATE? If there are no show stoppers found then they release it as final?

RC2 is final, they will release more RCs until they are satisfied, and the one that is fine for them will be called final

Sounds like RC2 is the one that is fine for them.

lets wait and see how long it takes for Firefox user-base to upgrade to ff 4!

i bet its going to be >>> faster than ie7 or ie8 users jumping to ie9.

if you ignore ie6 I still have no clue why MS is not forcing all ie users to upgrade to the latest version to help move the web forward! The single company which is pushing the web back is MS with a fragmented user base using ie6, ie7, ie8 and now ie9. Its a mess MS! get your act together! don't hold back the web!

That's because people have been trying to sue MS for autoupdates.

thats what im saying - web developers should stop implementing code to support IE6, and probably 7, this way the stupid users will be forced to change their browser

Tell that to the enterprise web application providers like Oracle and SAP. Get their web clients off IE6 and you'll see more enterprise customers updating.

Now we just have to wait for Microsoft to fix the awful font rendering with DirectWrite and then we can finally turn on hardware acceleration in FF4.

I'm sticking to Chrome and Safari though. Firefox doesn't really offer anything worthwhile.

Should have been fixed in SP1.

It isn't. The font looks terrible here with hardware acceleration. I have SP1 and all other Windows updates installed.

Would using gdipp help? I much prefer gdipp's text rendering over the default Widows style.
Potentially worth a try?

I haven noticed any font issues in IE9 since the RC. I have SP1 Win7. Use it as my default browser.

Same here.

I switched to Chrome because Firefox was so slow, and then to Opera because Chrome was so slow, unfinished, superficial, curious and so on - I call Firefox when investigating dangerous areas of the Web. Nice GUI but still slow and buggy (4 RC2)

Awhile ago I said Chrome is faster. Many Firefox fans jump on and want to kill me. Now, see many people use chrome.

Due to the test all over the internet, it looks like Chrome has the greatest and fastest javascript engine V8. But when it comes to real browsing, I really feel Opera is quite faster. But Opera UI is quite complex than Chrome. Keep using Chrome, though in free time, I always watch Opera for the lastest version and download portable version to test

+1 Many of us have Droid phones, and well it's just faster in most things. Some older Chrome users did not have hardware accel on, and they really need to try it now. Has anyone run FF4 on Peacekeeper, or another benchmark site?

IE 6 > Maxthon > FireFox > Chrome > ?

IE 6 was fine, until loads of crap, pop ups, viruses, malware, etc., etc., then Maxthon Added Multiple Tabs, pop up blocking, and for a while it was good, but cuz it's IE based, Maxthon started to crashed on me, after a while tried Firefox, everything was fine again, until it took 2-3 minutes to load in my Laptop, it is a great Browser, lots of great plugins and themes, but Darn! 2-3 freaking minutes WTF!, so i move to Chrome, took me a while find the extensions i needed, Chrome loads in 2-3 seconds (same computer). And I'm Happy now. All the updates are automatic (i think), Now the problem is Flash, but that's another Story.

Chrome slower then Opera? Since when?

since forever, if you dont trust me see for yourself, that said, even if opera is faster, its unpopular because it sux in ever other regard and it will always have small user base

I've tried Opera several times and every time I removed it from my PC because it was crap. No my internet isn't crap nor is my PC.
