Firefox 4 Beta 10 Lands

Mozilla have taken yet another step forward towards completing the widely anticipated Firefox 4.0, by making beta 10 available on their servers last night; but not before revising their beta plan, which could see as many as two more beta versions before the final lands in February. Firefox release manager, Christian Legnitto, had this to say in a blog posting yesterday, "This is the updated beta plan as discussed in the Platform meeting earlier today. It is a modification of the previous plan based on current bug counts and fix rates"

A final beta 11 can go ahead if all hard betaN blockers are completed before Friday afternoon PST (28th), which sticks to the original planning. However in the revised plan, a judgment call on Tuesday (02/01) will be made if hardblockers are not fixed before then and again on Friday afternoon PST 02/04.

If on Tuesday the remaining betaN hardblockers look at risk to land by Friday (2011-02-04) we will create beta 11 on Tuesday and plan on having a beta 12. Beta 12 will not have a fixed schedule and will instead be built when the remaining betaN hardblockers are at zero

Firefox 4, based on the Gecko 2.0 engine, will bring an updated user interface, new ways to organise tabs, a revamped add-on manager, support for HTML5 video standards, multitouch support on Windows 7 and a range of performance and security enhancements. The full release notes for beta 10 can be viewed here.

Don't forget that you can discuss this beta, and nightly builds right here on Neowin in the "Meet Firefox 4.0 (beta 10)" topic.

I **LOVE** seeing this much work and polish on software. Getting a hold of something rushed and incomplete is like a punch in the face. Beta quality "final" releases happen all the time. Some even end up never being updated.
Seeing Mozilla spend the last hundred years doing nothing but working on a thousand Firefox 4.0 betas makes me feel like when I install the non-beta build, it will work well.

eliminated the status bar for a crappy addon bar which take more space, there still a bug that i dislike a lot its that if i use menu bar the new bookmark button hides, and well as i said before i hate the default interface but i can customize it at least but the status bar its just something that should come back

If i wanted broken font rendering, i will use IE9 beta
No thanks. I don't need this crap..

If you wanted facts you would have shut your mouth rather than blabber about nonsense. Broken font rendering? Are you kidding?
Do you mean what Microsoft Windows Update had a fix for Windows, for?
I suppose you do not update your Windows, so no reason to update anything else either is there

I haven't checked out the many of the newer releases but in windows 7 does firefox still show a preview of each tab when the mouse hovers over the firefox window in the taskbar (like in IE8)?

It does. If you don't like it you can easily disable it in about:config, just search for preview and set "browser.taskbar.previews.enable" to false and they're gone.

Yes it does.

That is an annoying feature which is why you can disable it - and always could(the soul of Firefox!) - it appears to have been disabled or limited to one per window.
Some outdated info on disabling it here http://www.askvg.com/how-to-di...n-mozilla-firefox-3-6-beta/

The option is in the main options now: Show tab previews in Windows taskbar. It'll still do a preview for each window, but not each tab.

can i install the Firefox 4 beta along side the existing stable version?

would like to play with it but don't want to mess my existing firefox setup with all the plug-ins that are working for me wonderfully!

Yes, i've had it installed like this for a while. Would probably recommend backing up your profile just to be on the safe side though but no issues for me

Yes, but by default it would use the same profile as your normal firefox browser, same bookmarks addons and so on.

I don't think it will screw anything up, I've been using the betas for a long time and they work great, but to be safe you could use a portable version of firefox, just download from the link and extract to your desktop or something and you will have a fully independent firefox 4 beta 10

Thanks for your advise

I am on a mac here and found a nice little script to run firefox 4 beta using a secondary profile rather than the default being used on the 3.6 version.

found that most plugins i am using do not work on firefox beta so i cant really use it as my main browser, will help for testing purposes thought.

its nice to have 2 firefox versions running in parallel thought! once essential plugins i use are working i can start using firefox 4 full time

you can try installing the addon compatibility reporter, many addons work just fine, they just havnt been updated so they say they do and can be installed, with the compatibility reporter you can install them anyway

The newest version of minefield seems to finally put the tabs in the title bar.

When you enable small icons it actually takes up less space than chrome!

I assume you mean when fullscreen. This started last beta.

I admit that 11 or 12 betas seems a bit much!

If they're going to take years working on (what seems to me) a major change to the browser, I'm happy for them to take their time and knock out a really solid release.

Mozilla has a weird definition of beta. The quality of the earlier beta releases were more on alpha level to be honest.

Really? I've been using it as my main browser since what, beta 2 I think.
I've had very few problems. There are still some minor bugs in the tab groups which is where just about all my bugs have been...
