Firefox 4 delayed till 2011

Mozilla, creators of Firefox, announced today that they are forced to delay their up and coming version, Firefox 4. In May, the browser giant announced that the release date for the new version would be next month, although recent circumstances have pushed them to delay the release.

Currently, Firefox 4 is on its sixth beta release and will stay in beta until its first RC release which is said to be in early 2011. The final release is said to follow the RC(s) swiftly after.

Talking to The Register about change to Mozilla development mailing list, Mike Beltzner, headman for Firefox said "Based on the delays in completing the 'feature complete' Beta 7 milestone against which our Add-on developers and third-party software developers can develop, as well as considering the amount of work remaining to prepare Firefox 4 for final release, we have revised our beta and release candidate schedule,".

The Firefox community was said to have been informed about the circumstance and changes to the schedule were based on feedback. The new schedule was released into public domain. With Opera in the process of developing Opera 11, it seems the release of both Firefox 4 and Opera 11 could be released extremely close together.

I don't know if FF will have what it takes to get me to use it again as my main browser. I have tried to use the beta and even though I love the new UI, it's just not stable enough. Plus, right now I am using Chrome 8, latest Dev build and with HW acceleration turned on through the about:flags, it's a dream. Web pages load almost instantly, instant search, so much speed and stability and its a dev. When Chrome 9 comes out it will be game over for IE 9 and FF!

Aww I want beta 7 out so much lol. Beta 6 is horrible on sites like Youtube, the video always messes up
I would use the nightlies but for some reason "Minefield" as my browser annoys me
I hate the way Opera & IE renders pages, and I think Chrome & pre-4 Firefox are rather ugly
There is no win lmao.

Chrome is faster and with google sync i can switch pc's and my bookmarks and stuff follow me
And I much prefer Chomes tab's than FF's sytle

Have you played with their bookmark sync much though? I've sync between two computers, on one computer, delete an entire folder, it and stays on the other computer, then the original computer it was deleted from, comes back.

I love FF but sadly Chrome is better and I hardly ever fire up FF anymore....tried a few of the beta's and I have to say I can't see any reason I'll be switching back.

I tested out IE9... for about 3 minutes before it began to crash and attempt to infect my machine with malware.

Staying with FireFox all the way.

P.S. - Where can we get the nightlies?

LoL are you smoking something bad over there

After using IE9 and amazing UI of IE9, I am not looking forward to Firefox anymore, unless off course Firefox brings some more than IE9.

This statement really puzzle me.

MS did not need to bring some more for you to switch back to Microsoft world. Yet Firefox and Chrome team will need to bring some more for you to switch away from Microsoft world.

IE is good, what is the problem? I have FireFox installed on my laptop but only for testing purposes and some variety. otherwise, IE all the way on my main desktop.

I just by the time they release FF 4.0, they get rid of the new Firefox Menu. Could do without it, I like the Chrome's toolbar style saves a lot of space. =)

I was a truly Firefox user but since I updated it to the FF 4 betas ... I didn't hesitate anymore to switch [temporary] to Google Chrome. Now, I see it veeeery hard to switch back to Firefox.

All my add-ons stopped working and I can't really have a smooth web experience without them ... for me .. Firefox 4 betas are Mozilla's Vista >.> but hope they improve !

I hope FF 4.0 doesn't have as many memory leaks as 3.x did. There are countless times where I'd close the browser and restart it with the same tabs open only to have it use 1/4 of the RAM it was using before.

So it won't be included in the official ubuntu repos until 11.10 then. Sigh, that sucks.

It won't ever be in Windows Update though
And why do so many always say stuff like "That should be enough to hold me over until the final. I think..." and "ff will not be my main browser by then..."? I don't get it. Like they are fishing for a Mozilla official to come and talk them into...

I've wondered the same. Right now I use a combination of Firefox and Chrome. Firefox is my main browser and Chrome I only use for quick things. I am looking forward to this release and can't wait to use it.

Talk them into what?

I didn't say that with the intention of implying I was going to switch to another browser. What I meant was, I can't get enough of the improvements in the nightlies. .

Yeah, except it took Canonical like 8 years to even put 3.5 into Ubuntu after it came out.

8 years ????????? firefox 3.5 has been out june '09


you went them to include beta instead ?

LiquidSolstice said,

- Ubuntu hasn't been around for 8 years yet.
- They only do version upgrades in new releases, so that stability is guaranteed. All updates you ever get are bugfixes of versions and security updates. (so, it could only have taken them 6 months, max)

Sir, please get your facts straight before posting lousy comments. And then again, you can always add software yourself through custom repos, or just downloading them. (Which is what you need to do on windows in the first place anyway) - and as firefox doesn't require any compiling, I bet even you could get that done. :-)

I'm using Windows 7 x64, with nightly b8pre x64 as my default browser right now, flash it's working, using: flash square (http://labs.adobe.com/downloads/flashplayer10.html) , and java for windows x64 (http://www.oracle.com/technetw...va/javase/index-137561.html), still with some problems, some of the old addons i used to have in 3.6 dont install, takes some time to load.

I speed up the loading time moving the cache, main program and profile to a ramdisk, still takes sometime to load, but it's munch better now.

And For the Addons, i'm just using the ones compatibles and the ones in development or beta stage.

Firefox sync works really nice.

No crashes (internet explorer 8 32 bit crashes after sometime most of the times )

Thank you to all the developers for this great browser!

Firefox 4 b8pre Main browser for now!! :-)

I don't know about beta 8pre, but beta 6 is really buggy. Also, to be fair, you have to compare it to Internet Explorer 9 not 8.

I'm using the latest nightly x64 as well. It is more stable but it does have a ways to go. x64 is great, I like how it's faster than the 32bit version.

Firefox has lost its appeal to me. Originally it was my default browser because of better standards support, faster updates and customisability. Now Chrome has overtaken Firefox in pretty much every respect. It's not as customisable but it's so much more visually appealing by default that it's not an issue.

Firefox takes far too long between versions, especially for what little they add. Standards compliance has slipped, performance is lagging and the new UI direction is questionable. I think it shares a lot of the problems that drove people away from IE.

You really need your eyes checked if you somehow think the UI of chrome is any better or visually appealing in the least.

Though I agree on the update schedule, this version they are doing a lot. The changes to the addon system alone are worth it for me. I am really looking forward to this version.

Sure, let Google know everything you do on the web, not like they're creepy or anything, oh wait they are!

How so? It doesn't have all the crap you don't need to look at.. its minimalist and it works..

and this is coming from someone who even preferred IE over FF

Chrome being a massive piece of spyware is as old as "vista is DRM infested omggggg stay away from it".

Some people like simple UI's and there are people around you with a different taste than you.

I'm using beta6 right now and I have to say it's pretty awful. Things don't render correctly and I'm constantly freezing/crashing it. Hopefully this is resolved in the final version.

I think it's things like that that caused them to delay it...

It would hang when I select a text box. I sure want to know what is going on.

Darn why do they always have delay things

hopefully Firefox can keep up a bit. only reason why i should switch to a other browser is a good Adblock Plus alternative or something.

The delays are partly due to some the crazy ideas from the UI team which got implemented and then got dumped ..

Direct x acceleration also hit probs plus some other show stoppers so quite a few bugs guys

I think so too. It sounds like they're putting a lot of work into this version. I can't wait for it to come out. It's a shame it's been delayed, but I think it'll be worth it.

Yeah but will it loose it' fan base by then?

I know many a game that has been delayed and delayed, then flopped when released as people simply lost interest.

It's kinda sad to see. They need to get back on track. Compared to IE9 beta, any version of chrome, and possibly opera, Firefox is slow as hell, it hangs and it's buggy. And that includes version 3 too.

Firefox 4 beta 6 is really buggy: it constantly hang and crash besides eating up to almost a gigabte of RAM. I was shocked that Internet Explorer 9 which is till beta 1, is so much more stable.

Maybe about the beta versions (I haven't used them), but your remarks are definitely off the mark about the 3.6 stable branch. If it hangs or is buggy, you need to check your profile and/or extensions. As for being slow, that's only in the benchmark scores department. Firefox 3.6 is absolutely competitive with Chrome and Opera in terms of real-world page loading speed.

That's right, I'm sure your main browser will be the *current* best browser, Firefox 3.6!

I guess Mozilla is quivering in their boots.

that's the bottom line ... seems to be the most all around best browser in terms of speed/general smoothness etc based on my use on my AMD Athlon X2 3600+ (2.0ghz overclocked to 2.4ghz) CPU.

i like it better than Chrome/Opera for sure overall. been using Firefox since just prior to the v1.0 release as my primary browser and damn near only

Yes. This. Probably will have moved onto Chrome by then.
As soon as they fix the bookmarks, I'm over!

No surprise really. I've been using the nightlies and they've been great so far. That should be enough to hold me over until the final. I think...

Are the nightlies better than b6? b6 runs awful.

Couldn't agree more, b6 is like a nightmare. I'm really not surprise of the delay either rather happy that they will have more time to work on it to fix as many bugs as possible.

Xilo said,

The nightly is labeled b8pre, and I've read that there's been, "hundreds upon hundreds" of bug fixes between b6 and b7 alone. So without knowing exactly what's been awful about b6 on your end, that's about as much as I can offer on that. I hope that at least sounds encouraging.

Wow, that sounds great. I think Firefox 4 is going to be a tremendous release. It sounds like Mozilla is really putting a lot of work into this release. The changes to the addon system alone sounds great.

I don't know what you mean by such a general statement but the nightlies have been overall pretty good. When you run nightlies bugs can and DO crop up but they usually go away within a few days too. The big improvement since b6 is that the new javascript engine was put in and they've done some major progress on their javascript speed which you can see at http://www.arewefastyet.com
