Firefox 5 released

Almost three months following Firefox 4's release, Mozilla has posted final builds for Firefox 5 ahead of the official release date of June 21. The new accelerated release schedule Mozilla is using for Firefox development will see the next version of Firefox, Firefox 6, go into beta about two weeks following Firefox 5's release.

The new release looks and runs very similar to Firefox 4, but it has a few changes under the hood. The official changelog will be made available here.

  • Support for CSS transitions has been added
  • The preference for "Do Not Track" has been moved to aid easier discoverability by users
  • Improvements for canvas, JavaScript, and networking performance, and memory usage
  • Improved standards support for HTML5, XHR, MathML, SMIL, and canvas
  • Improvements to spell checking for various languages
  • Improvements to Linux desktop environment integration
  • Performance improvements for background tabs
  • WebGL fixes: a fix for cross-domain textures and a fix to address the memory stealing issue

While Mozilla is pushing out new updates for Firefox, it is also working on a plan to end support for Firefox 3.5, which is now almost two years old. Users that are still on Firefox 3.5 may see a forced upgrade to 3.6.18 in the coming days.

I can't download it. Getting the following on Chrome:

This webpage is not available
The webpage at ftp://ftp.mozilla.org/pub/mozilla.org/firefox/releases/5.0/win32/en-US/Firefox%20Setup%205.0.exe might be temporarily down or it may have moved permanently to a new web address.
Error 601 (net::ERR_FTP_FAILED): Unknown error.
Any ideas?

Same thing here, looks like they've restricted access to the executables. Might not be final build after all?

Not really interested in FF anymore. I was once a very dedicated FF user but the higher their version numbers get the more disappointed I become. It's turned into a bloated, slow pile of junk. When they released FF for Android mobile that was the final straw for me. I switched to Chrome and haven't looked back. FF need to smarten up!

At least they could change the theme. I hate that orange Firefox box button at the top. Firefox is my favorite but they really stepping into wrong way by the fast version changing policy.

the acid 3 test was much faster although the test result came up the same... it's an improvement in rendering speed which is always welcome.

and still no x64 for Windows

i dont think they want to waste time on 64 bits version. you know, flash for example isn't 64 bits. so even though 64 bits its nice like in IE, since i use justin.tv alot, i cant even see their chat because it needs flash.

too bad im still waiting for xul migemo extension to update, i have find an alternative, i used that extension to make search look like safari search where they highlight what im looking for and darken the rest

I just went to mozilla.org and it still shows v4.0.1 - NO version 5.0 yet.

5.0 final is already on the ftp servers but the release hasn't been announced yet

The ftp mirrors are not meant for us, they are meant for mirror sites. So guys, unless you're doing Mozilla and fellow Firefox users a favour by hosting downloads on your own web servers, please stop using the ftp links.

It's not released yet. Why do so many sites jump the gun??? The official release may (or may not) be June 21st. In any event, It's only officially released when you see it here: http://www.mozilla.com/en-US/firefox/new/

Yep, may have been signed-off as final but no word on the home page, no release.

Wow relax guys... all my addons working fine surprisingly.
FIREFOX SYNC: It is now built in to firefox you can remove legacy extension
TEST PILOT: Renamed feedback 1.1.2
Firebug: Get b3 from getfirebug.com

These days I must wonder why people are so anal about version numbers and more regular releases. Does it impact your life in some way that this is Firefox 5.0 and not Firefox 4.1 or 4.5?

Been a Mozilla/Firefox user since Mozilla 1.5, but Firefox 4 was so bad it finally made me switch to Chrome. Now that I've gotten used to Chrome, I don't see me moving back....

Stupid.

What's the point in changing a major version number for a minor update? You're not fooling anyone into thinking this a big update, Mozilla..


Did anyone say they were? If you have realized by now that version numbers are all but useless when it comes to browsers...then there surely is no help for you.

You can blame Google for that.

Mozilla's version numbers were fine before. Version 4 to version 5 implies a major update. Should be version 4.2.

Firefox 4.0 is okay-ish. Few steps back from 3.6 but overall good. The last good 3.6 was 3.6.12 after which they implemented addins like Flash in a separate process. The result? Instead of Flash crashing Firefox, Firefox started crashing Flash.

Flash is a big problem on Chrome too, consumes lots of memory, crashes the browser, uses too much CPU. Just get rid of this software, HTML5 will help the browsers a lot.

Are they copying chrome with such fast version increments? There was a time when 3.0 -> 3.5 took longer than 4 -> 5.

They're copying their release cycle, to get new features out quicker. This is a welcome change, as it is my understanding that the bigger changes can cook longer while we can get the already made stable features sooner. It's like having your cake and eating it too!

As somebody else said, the minor changes don't warrant a major version increment. If they carry on at this silly rate they'll be at Firefox 20 in a couple of years.

anyone else having problems with FF5 and Facebook? every time i open a photo while a YouTube video playing in Facebook the video restarts. same when i close the photo

I'll be glad when every browser developer is implementing a new release schedule so we don't have to hear a thousand "LOLWTF? Bring on version 3847 already!!" posts every time the version gets bumped.

Firefox 5 isn't officially released yet ... it's still Beta with the Release Candidate(s) coming up.
The finalised release of Firefox 5 should be coming sometime after ... or, when it's ready.

The article, and it's headline, are misleading and untrue at this time.

No, it's not misleading. If you look closely at the download links they are in the "releases" folder. So they are the final builds that will be officially released on Tuesday. So Neowin has not mislead anyone.

Not necessarily ... just because they're posted in the "releases" folder on Mozilla's FTP server,
doesn't always mean they're the actual finalised builds. If any "showstopper" bugs are found between now, and official release date, these builds can be pulled without prior warning.

By all means, download and test these builds that are available now, but be aware, Mozilla
reserves the right to withdraw them from the server at anytime. Although, I generally don't
recommend everyone downloads the binary files direct from the FTP server, as this can
place a potentially unnecessary strain on the server.

So, at the very least, the headline is still misleading. Firefox 5 has NOT been released yet.

True. If a showstopper happens, then it can be pulled. However, they don't post to the releases folder unless they believe it to be a release to the public. It is just a matter of getting web pages updated and making it "official".

How I see it, despite the version numbers which don't mind me at all:

Fx 4 was a major overhaul. Certainly provided increased speed, improved mechanisms in relation to 3.x but being extremely new, time was needed.

Fx 5 is like a major optimizing update for 4. We could say this version is 4.1. and important to fix Fx 4 glitches.

The newer numbers ( 6, 7 ) from now will be bringing fixes of course and will introducing carefully/slowly new features.

Already planned new, improved Hardware Accelerator and part of JavaScript engine.

Overall I think Chrome did a good thing on Fx. They woke up and moving a bit faster than usual. With time Fx will be more than perfect.

I agree, it's good to see them moving development faster. While this new cycle may take a bit longer for others to get used to, it's a welcome change!

Stop the troll guys!! The features added are nice , FF5 is faster , supports more HTMl5 and CSS3 animations , and has more memory leaks fixed and faster startup boot. That makes it pretty much a good browser for daily use , it aint ages slow than chrome etc anyway! If you don't like it , then tweet it but dont ruin this discussion flooding with crap

I'm sorry, are Firefox users not allowed to worry about their browser of choice? I'm pretty sure everyone here wants to see Firefox get better, not worse...

you think ff5 is worse ? Firefox IS getting better , its just that it's "development" methodology is changed, which u might call worse , but trust me to even see CSS3 animations and memory leak fixes with old development track would have taken a year! This way audience can check out new features , quickly , report , and get them fixed again quickly in next version , overall improving stability.

"Accelerated development schedule" == "change the version number 4x as often."
If by that you mean ... release 4x as often, yes.

Installed, it crashes every time a webpage is loaded completely.
Safe mode isn't working either.
Falling back to 4.01, I'll wait a little longer...

Chrome and Opera have extensions break a lot too.

Never had any extensions problems from day 1 with extensions on Chrome.
Had many with every version of Firefox and still have some not compatible with FF 4.

max22 said,

I use both Firefox and Chrome, but I've never run into a broken addon in Chrome, and I use the Dev builds. I've kept Firefox on release builds only, for stability if Chrome ever experiences a problem and also because I hate managing the addons between builds.

Then you don't use a lot of extensions like my friend. Oh yeah you can sync add-ons in Firefox.

I use what's necessary. My bad if necessary doesn't include 50+ addons.

I don't use 50 add-ons either. The necessary add-ons break on chrome and opera as well all the time.

Lemme know when you're speaking from your own experience, and not your "friend".

The real strenght of firefox over IE and Chrome are the extensions, but with this fast major release will they keep up?

zikalify said,
so title is false, should say firefox 5 rc released

Title is NOT false in that the final release is done and posted.

RC came out 3 days ago -- ftp://ftp.mozilla.org/pub/firefox/nightly/5.0-candidates/build1/

5.0 release can be found here -- ftp://ftp.mozilla.org/pub/firefox/releases/5.0/

Notice that the RC was under the "nightly" folder. The final release is under the "releases" folder.

But if you want to download, they don't want people hammering the ftp protocol/ftp server. So, instead of using the English US Windows link ftp://ftp.mozilla.org/pub/firefox/releases/5.0/win32/en-US/Firefox%20Setup%205.0.exe, replace the ftp protocol with http and use http://ftp.mozilla.org/pub/fir...S/Firefox%20Setup%205.0.exe

yowan said,
Where is the official windows 64-bit build. FF5 was supposed to be the first official win64 version

Yeah I was wondering the same thing. The only browser to officially have 64 bit is IE and it is a half ass job at that. Safari too but that is only for Macs at this time.

Lamp0 said,

So no 64 bit until FF7? I thought it was coming much sooner.

You can just use this beta. No flaws whatsoever and rocksolid. Only need to set compatibility check to No for extensions to work. And they will work with this release.

I've been using FF7 64bit with no problems at all, no crashes, no addon problems, so far it's perfect for me.

Why Mozilla? This is just going to make the addon-developers go nuts... and you will lose them. They are your big advantage over the other browsers!

A mechanism is on its way to solve that problem , automatic bumping of version probably

in case you dont know the addons work even on the latest alpha versions of Fx and unless Mozilla completely changes the architecture of the browser, like using a new rendering engine, etc .. addons will still work, they just have to be forced on the new versions, if you didnt knew that, now you do, so next time save yourself the trouble of making blatantly foolish statements

bogas04 said,

Already being done. Addons were bumped for Fx5 compatibility a few weeks back.

5 was meant to be out of Beta, there wasn't even an RC
The beta stage is essentially includes RC stage now.

There was an RC, it came out 3 days ago.

They aren't that far off - maybe not the end of the year, but early 2012 is probably the target... unless Windows 8 hangs it up.

Biggest problem with this fast release schedule is going to be extensions stop working unless developers can keep up or you set the option in the about:config and risk compatibility issues

That's why chrome is better, extensions dont keep breaking. Mozilla need to hurry and fix this!

zikalify said,

they need to update their addons so users dont have to restart after installing one for starters... and remove the compatibility checker, because addons work on the latest - Nightly 7.0a1

zikalify said,

Actually chrome extensions break all the time too. Even Opera. I go to the chrome galley just fun and laughs. It is great when finding one that doesn't work anymore. There so many to list I don't even have enough room here. Same with Opera. Same with Firefox. Does it matter ? No. About 90% of the time at least with Firefox new add-ons show up to replace te unsupported ones.

Aaron44126 said,
Actually, they auto-bumped the compatibility version for lots of add-ons. This should get better over the next few releases.

Here's hoping. Hate having to manage addons with Firefox in this manner.

allwynd said,

...

They added that functionality in 4.0, authors just have to make use of it.

It's a tad faster for me. Starts up good so far without any extension. If it stays like this after installing ad-block plus and does not give me "Not responding" crap, I'll return to Firefox from Chrome.

allwynd said,
the best browser out there

Agreed when looking at the overall smoothness of the browser and some occasional add-on stuff.

but i will see if memory usage improved at all as i noticed Firefox 4 seemed to be a little heavier on RAM than it previously was as if your leaving it running all the time and slowly load random sites etc etc it seems to keep inflating on RAM use more and more and when you got a 2GB system that can start to get a little noticeable.

Echofon uses a binary extension (for some reason), which means they have to manually update it to work with new versions (while most other extensions are updated automatically, unless they'd break)

Oh look, FF9000 will be release by the end of this year. The improvement? The help dialog background will be change!
I am disappointed at Mozilla by submitting into the pressure. Instead of innovating the browser, they are becoming a me-too company. They still think Microsoft IE is their main competitor. I'll still be using FF3.6 and will continue to do so until FF9000+ improve their rendering responsiveness.

Neobond said,
Now my Echofon extension just needs updating

try this... http://goo.gl/r6G02 (it worked for me on one of my extensions that got disabled)

basically do what the article says but instead of where it has "extensions.checkCompatibility.4.0" put "extensions.checkCompatibility.5.0" instead.

i am pretty sure that will fix your problem (if that don't work odds are your extension just wont work without a update. but i think the odds are good that it will work since it will basically force Firefox 5 to try running it. plus if you notice after doing that where the Firefox drop down menu is when you click on 'add-ons' it will now have a message saying... "add-on compatibility checking is disabled...")

Thanks for this. It's a much easier solution than editing the install.rdf files.

So far everything seems ok apart from it yet again wiping out my pinned bookmarks on the jumplist. It's hardly worth using this feature if they're gonna clear it every time there's an update.
