Hi my name is Johnathan Nightingale. I am a Director of Firefox Engineering here at Mozilla.
I'd like to talk to you about What's New in Firefox 4.
The first thing I want to talk to you about is Speed.
It all starts with our Jeagermonkey Javascript engine.
It's the fastest we've ever ship.
It's up to 6 times faster than our previous versions of Firefox.
We've optimized our start up times,
we've popped up a lot sooner to get you on the web.
We've added Hardware Acceleration.
So interacting with pages, scrolling them, switching between a large number of tabs
The next thing you are going to notice when you install Firefox 4 is the new streamlined user interface.
We've made it a lot cleaner and it takes up a lot less space.
We've got rid of the firefox menu. We turned it into a button up in the top corner
It's just got the most frequently used things, the things you need most.
We've also made some changes to make it easier to get around when you are browsing the web.
The first one of these is the Switch to Tab.
When you have a bunch of open tabs in your browser and go to open something new
Firefox will tell you if there's already a copy of this tab that is opened.
For sites that you are living in all the time,
things like your email, your social networking sites,
We've added the feature called App Tabs,
so that you can right click and turn one of these things into an App Tab.
and make sure it's always available. It's pinned to the left end edge of your user interface,
It's really easy to jump back to it
and not have to go searching through hundreds of tabs for it.
And if you do have a hundred tabs, you're gonna love Panorama.
It's this new feature we've got that lets you organize your tabs into groups
You can drag and drop them.
Focus on one set of work at a time.
Instead of having to move all around your tab strip to get to the things you care about most.
All in all, it just makes it easier to browse the web
and live more of your life on the web.
Customization has always been a big priority of Firefox.
But in Firefox 4, we've made it even easier.
You can see the new Firefox 4 Add-ons Manager
includes all of your extensions, all of your plug-ins.
It also includes a search interface to help you find new add-ons and new ways to make Firefox your own.
One of the killer features we've added in Firefox 4 is sync.
We support the ability to sync all of your personal information between your various computers
So, if you've got your home computer and work computer or maybe if you've got an Android phone,
Firefox Sync lets your push all of your history,
bookmarks,
your saved passwords,
even your open tabs between those machines.
So it's really easy to get up and go
And have the same Firefox no matter where you are.
One thing that's different about the way we built sync,
is that all this personal information that's moving between your machines,
is encrypted locally before it hits the internet.
That's just part of our ongoing dedication to make sure that we're always doing as much as we can
to keep you safe when you are browsing online
and to make sure your that private data is your own and it doesn't belong to anybody else
And for web developers, Firefox 4 is the best we've ever shipped.
It's got an amazing array of open web technologies for building beautiful interactive websites online
HTML5, CSS3, Downloadable fonts, even WebGL for 3D accelerated graphics
This is the future of the web.
And it's never been easier to build incredible stuff online.
We're really excited about Firefox 4.
And the stuff I've talked about today is just a sampling.
Get Online.
Check out the feature list.
Grab a Copy and Take it for Spin yourself.
We've built it for you and we want to know what you think.
We think it's the best Firefox yet.
