Your guide to Firefox 4 and its shiny new features

Unlike Firefox 3.5 (private browsing) and 3.6 (personas!!), version 4 has a significant number of new in-your-face features -- features that will take a little getting used to... like tabs-on-top! There are tons of neat little additions that improve your surfing experience, too. Many of these will exist in the background, under the hood, but it still helps to know exactly what your new browser is capable of; did you know that Firefox 4 is as fast as Chrome, for example?
This guide will fully prepare you for Firefox 4. It will teach you how to work with the big-hitters Panorama and Sync, and also introduce some other features you might not have heard about. If you're already using the Beta, this guide might teach you some new tricks. If you're holding off until the official launch in 2011, that's fine too -- bookmark this page and check back later!
You might find, after reading this guide, that you suddenly feel compelled to try out Firefox 4. It really is rather good.
The Big New Features
Firefox 4 has a bunch of really cool features that elevate it way above the competition in terms of functionality. While Chrome and Internet Explorer 9 are banging the performance-performance-performance drum, Firefox is sticking to its guns: if you want a feature-rich browser that adds to the surfing experience, Firefox is still the browser for you.
In the cloud: Firefox Sync
If you move around -- if you ever use Firefox from more than one computer -- Sync is one awesome addition to your workflow. When you use Sync everything -- tabs, passwords, search history, bookmarks -- is saved to the cloud. If you open a tab at home, and then go into work, that tab will be open on your office computer. Sync also works with Firefox Home for iPhone and Firefox Mobile for Android.
To enable Sync: head to Tools > Options (or Big Orange Firefox > Options) and hit 'Sync'. An easy guide will walk you through the setup.
JavaScript engine optimization: JaegerMonkey
Hot on the tail of TraceMonkey, JaegerMonkey or (JägerMonkey) adds a nitro boost to Firefox 4's SpiderMonkey JavaScript engine. The exact performance gain brought by JaegerMonkey varies from benchmark to benchmark, but one thing's certain: Firefox 4 now has very, very competitive JavaScript performance.
If, like me, you gravitated towards Chrome because of its superior JavaScript handling, it's now time to give Firefox another go. Those JavaScript-heavy websites like Google Reader, Gmail and Facebook all perform very well in Firefox 4. In some cases, thanks to some skilful tweaking, Firefox actually feels faster in some cases -- a very weird sensation indeed.
Tab management: Panorama
After the release of Firefox 3.6 a big change occurred behind the scenes at Mozilla: Aza Raskin took the reigns as the Creative Lead of Firefox. It might be too much to say that he is the sole reason behind the deluge of new features in Firefox 4, but he's certainly a big part of it. Panorama is his main offering for Firefox 4, and if you haven't used it yet you're in for a treat.
Panorama harnesses our spatial memory to provide a completely different tab management paradigm. Instead of a long line of almost-identical tabs, often in an arbitrary order, Panorama lets you organise them into groups. But then it goes one step further: it lets you move those groups around on an imaginary table. Groups can be any size and placed anywhere.
The idea is that you can break your surfing up into fairly logical groups -- work, fun, research -- and then keep those task groups separate. Distractions are kept out of sight, out of mind, and you don't end up 'multitasking' between work, Gmail and Facebook...
To activate Panorama: hit the odd-looking 'window' button in the top right corner. Alternatively, use Ctrl+Space.
Hardware acceleration
While Firefox has never jumped up and down on the performance-performance-performance soapbox, it has always been competitive -- and hardware acceleration is no exception. With Firefox 4 you don't get quite as much acceleration as Internet Explorer 9, but you should still see significant improvements in rendering and page-scrolling speeds. The speed-up will be most obvious on complex websites or 'Web apps' that eschew Flash for HTML5 and CSS3. Fonts (and font scaling) also look a lot smoother, too.
For now, only Windows is fully hardware accelerated, thanks to Direct2D and Direct3D. Some parts of Firefox 4 for Mac are accelerated with OpenGL, but it's not clear whether everything will be accelerated by release time. It remains to be seen whether Linux will also be accelerated with OpenGL -- it should be!
At long last: restartless add-ons
There are two big gripes that people have with Firefox 3.5 and 3.6: it's slow, and add-ons require a restart to install. Is Chrome's growth really such a surprise when you consider its performance advantage and its restartless add-ons?
Well, with Firefox 4 both of these problems have been addressed. Performance, as already discussed, is massively improved -- and thanks to the new Jetpack add-on build environment, restartless add-ons are also here!
Unfortunately this change doesn't make all add-ons restartless. Add-ons need to be specifically coded to be restartless -- but hopefully add-on developers will rise to the challenge and begin the process of making every add-on restartless!
If you want to see restartless add-ons in action, grab a copy of Firefox 4 Beta and install Mozilla Labs: Prospector - Speak Words. Prepare to be amazed.
Extensive HTML5 and CSS3 support
Last, but most definitely not least, Firefox 4 retains its excellent record of standards compliance. Whether it's newfangled HTML5 video or audio, or drag-and-dropping files into Gmail, Firefox 4 has you covered.Firefox also has great CSS3 support, which brings 'Flash-like' animation to standard website elements. Hardware acceleration helps here, too! You will begin to see websites that look like Flash, but aren't -- that's CSS3 at work. If you want to see what Firefox 4 is capable of, the Internet Explorer Test Drive is probably the best way.
The age of HTML and CSS rich-media apps and games is finally here. Hold on tight: Firefox 4 is biting at the bit and raring to go.

What does " Firefox is sticking to its guns: if you want a feature-rich browser that adds to the surfing experience" mean?
Chrome has better features than Firefox (at least the ones who matter), whatever feature Firefox launches there's one for Chrome 2 days later...
Most extensions on Firefox are right inside Chrome (Greasemonkey anyone?)
HTML5 support? last time i checked Chrome was the browser with the highest support on HTML5 243 points on http://html5test.com/
Chrome extension support is better, Web Apps work better on Chrome (Firefox so called webapps are just what we call Pinned Tabs in Chrome since 1874 so it's not really a new feature) - real web apps (at least for what I know) are written in Ajax
Sync? Doesn't Chrome does that already for ages?
The one thing I can let Firefox be better is just 2 things the javascript engine (which I'm not sure who's faster since I'vent heard about real tests being made between Chrome 9 and Firefox 4b7) and the fullscreen mode in which the URL show up on mouseover
In case someone does not agree with I'm saying feel free to discuss... but before that just one word: OMNIBAR (you're future arguments are now, invalid)
João PereiraNov 11th 2010 1:27PM
forgot one thing, as it may not seem so important the new Firefox button on the upper corner is kinda annoying... what kind of dropdown menu appears in 2 columns?
and btw dunno if there is anything like that on firefox but about:flags kinda rocks
Sebastian AnthonyNov 11th 2010 1:42PM
Yeah, the two-column tool bar I'm not too sure about. And hey, the orange button is STILL sitting up there at the top stealing valuable screen space.
The Omnibar is the single reason I still use Chrome. A browser needs more than one 'killer' feature, IMO :)
NightHawkNov 11th 2010 1:52PM
You know, I really hoped your comment would have been constructive, but then the HORDE of grammatical errors, random blabber about 1874 and "are right inside Chrome" made me come to this conclusion: you are a sad fanboy.
Keep this in mind: better products lead to even better products. Praise evolution, don't kick it in the nuts. Accept the fact that others might do some things better. Try and SURPASS the odds. Don't diss.
João PereiraNov 11th 2010 2:08PM
I'm sorry if my english is not perfect :)
I am just saying you can't say Firefox is better for the user experience IMO since most of the features are things that Chrome has since a long time (Sync has existed since Chrome 6 if I'm not mistaken, pinned tabs since Chrome 5) and that Chrome has lots more native support than Firefox (not sure about this point though) but examples like Greasemonkey or Prism show that Chrome has features inside the browser and that you need a extension for them in Firefox
Another thing, the thing that was called Web App Store by Mozilla is not the same as Google called 1 year ago, at least it seems like it: one of the changes in 4 was that Web Apps were supported (and for what I seen that are just Pinned Tabs) and Chrome Web Apps are supposed to work like Native Applications (normal OS applications).
What I tried to say was that you can't call Firefox the best in user experience by the factors included in the post and most Mozilla has been so cheery about lately, they're the same as in Chrome... Just Saying
NightHawkNov 11th 2010 3:16PM
Prism was originally made by Mozilla. Greasemonkey was originally made for Firefox. There were quite a few extensions that allowed syncing before Chrome got them.
I won't deny the fact Chrome implemented them in the core experience, but that is irrelevant overall, considering it was AFTER someone already made said things. Many people don't need to sync, for example. Others have no use for userscripts.
As for best user experience, that is in the eye of the beholder. I hate the Chrome interface, for example. I don't like the omnibar. I want to rearrange the GUI, but I can't. Again, a personal preference. You like Chrome. Do you speak for the rest of the world somehow?
João PereiraNov 11th 2010 3:55PM
I do not speak for the world... Just like the person that posted this does not, I just gave my opinion and like he said Firefox is the best for User Experience I say is not (it's just our opinions)
Greasemonkey and Prism were made first for Firefox like Sync (I don't recall any sync extensions, if you please could indicate some) and Pinned Tabs were made by Google...
The point about your GUI is a valid point (one of the strongest aspects of Firefox), and btw you probably can do it with Chrome (but it's harder since you probably have to dwell in the Source Code)
By the way why don't you like the omnibar? I'm just asking because I can't really point nothing bad about it just wanted to know your opinion
JoshNov 11th 2010 4:13PM
Browser wars: leading to meaningless comments since 1994.
RahabibNov 11th 2010 4:39PM
ah I wish I could like Chrome.
lack of GUI config, Lack of sidebars (although they have been promising it for the last 2 versions and its still gone), bookmark management sucks for people who have lots of bookmarks (tags, seperators, and the ability to drag and drop to folders - with a sidebar).
Chrome is nicer however, faster (although with FF4 I would have to see), I actually like the sync much better, I love most of the extensions that - many are not on FF.
so its all down to taste. Ill still use FF until Chrome starts adding in a few more features (sidebar bookmarks mainly). I dont care if its by extension.
samNov 12th 2010 1:00AM
Web Apps ... that's the the total BS feature, basically launching a web pages from the desktop LOL
And Chrome DOESN'T have many of the extensions in Firefox.
Also, Chrome (being Google) give significantly lesser options to users, has a much worser bookmarks and history manager. And with the bungled flash and privacy concerns its a pain in the a**
Panorama Tab feature of Firefox 4 is nothing like what any other browser has.
Also this article forgot to mention that "The new beta will work on Windows XP, something most other hardware accelerated browsers can't do, and it will work on Macs"
Yea that's why Firefox beats Chrome. Chrome only had the JavaScript Speed advantage over Firefox. And thats now Gone.
samNov 12th 2010 1:09AM
Not to mention that Omnibar is just the the merging of the address bar and a search box.
Hybrids never really suffice. With a separate search box its much easier to switch search engines (just I Don't use Google 100% of the time ... shocker). Also the display of search results separate from history results is a cleaner display.
Also to say that Firefox is adding features that were in Chrome is true, but the question is who will go it better. As history has shown, my money is in Firefox.
BTW. do you have any idea how many Features of Firefox Chrome borrowed when Chrome first appeared (they did some better true) but they based many features on Firefox and not IE.
*I will not continue this argument. Firefox Rocks. And a relatively stable loyal user-base for 3.6 even in light of Chrome being significantly better proves that people get something more from Firefox. http://marketshare.hitslink.com/browser-market-share.aspx?qprid=1. Now that Chrome is no longer the super fastest, it will be interesting.
João PereiraNov 12th 2010 4:36AM
I never said it has more, I just said the ones that are more popular in FF there's an alternative in Chrome
Web Apps are not what you described, that's what's called Application Shortcuts, Web Apps (and I'm not really sure here) reload whenever there's an update to the page (they might do more stuff I'm just not aware of it) so don't compare what Prism can to what Google wants to do with Web Apps (and btw the Chrome alternative to Prism is a 3 clicks built-in feature)
Like I know what I'm talking about cause I actually test stuff before rambling about it, I know that there's no good alternative to Panorama on Chrome (all the extensions that try to do it don't seem natural)
You're really saying the search history showing up separately helps (a lot)... I would like to know how...
Panorama is better there's no way I can say the opposite, but omnibar is also ("Don't use Google 100% of the time" - your discussing 2 browsers and you never tried it once lol that's the real shocker)... What can you do in FF search bar that you can't do in Chrome Omnibar? First of all - yes you can add other search engines and make them switch using keywords (not clicks!!!), if you don't use Google you can change in the settings for whichever you want (I kinda changed it to IMDB right now just to make sure) - and most of the sites (I say most because it worked with Kongregate, Facebook but not with DownloadSquad) are automatically added so if i write Kongregate.com + space + Little Kitties from Hell - it searches Little Kitties from Hell in Kongregate
If my explication on what the omnibar can do was too confusing just ask me for any clarification^^ but I actually tried to use Firefox Search Bar before commenting - try to do the same when you comment yours - it helps to know what you're talking about
NightHawkNov 12th 2010 11:28AM
While I like keeping things minimal, web search and history search are definitely 2 different things for me. I can't stand seeing search suggestions / results in the address bar. I like to see the search results all nicely aligned in a big, independent tab. And I search with keywords, as it's quicker overall. But that's just me. Oh, and I also have tons of bookmarks. I search through them via de address bar.
Royce BarberNov 15th 2010 1:48AM
"Sync? Doesn't Chrome does that already for ages?"
Your statement really bothers me, because Google made you believe it does something that it not only can't, but it does the opposite: It DESTROYS bookmarks every time you "sync". Google lied to you. They viciously lied to you.
I'll say it again to be very clear: Chrome does not sync. Try it. Go ahead. You'll find that it bugs up every time. Research this. Chrome will also bug up a folder in your GoogleDocs, adding all your bookmarks, making them permanent forever unless you do a fix which doesn't always work. Want to delete a bookmark from your Chrome while Sync is enabled? Too bad, you can't, it comes back with six copies. Try deleting those. Too bad! You can guess what it does.
And don't tell me the Beta Chrome fixes this - it just makes it WORSE. I know Chrome, I love and use it continually. It does amazing things, but it does NOT Sync. It will NOT Sync until Google takes it's customers seriously. And I say customers, because we look at Google adds all day long, and Google knows a ton about us, and also I pay for extra Google storage, among other Google products.
Another thing that ticks me off is that it's not possible to insert images into spreadsheet cells on GoogleDocs. But thats another story.
This rant is more about Google than about anything you said. You're innocent as far as I know. But please, don't ever in your life suggest that Chrome has SYNC. At least not until it does and then some. And refunds me countless hours lost fixing thousands of bookmarks.
All that said, I do use chrome daily, and I do love it dearly. I just don't love the evil broken sync. For sync all good chrome users use the plugin Xmarks. I don't work for xmarks, or even care if they survive, but they work well.
João PereiraNov 15th 2010 3:19AM
Got sync enabled all the time and have deleted several bookmarks... newsflash they aren't here anymore... that bug never happened to me but that might happen because I use Chrome Dev since it was on version 5 (3 on stable) which was the first to bring up sync if I'm not mistaken
SpankyNov 11th 2010 1:45PM
This browser hauls ass. I'm done with Chrome.
Where's my Omnibar plugin so I can make this my default?
Sebastian AnthonyNov 11th 2010 1:46PM
https://addons.mozilla.org/en-US/firefox/addon/8823/ -- but not available for FF4b7 yet :(
Soon hopefully!
rokicNov 11th 2010 5:32PM
Actually, Omnibar add-on works just fine.
EuropeanNov 11th 2010 2:10PM
Is it just me or are the fonts still messed up? The rendering is horrible! And it looks like it will stay this way since this is the last beta...
vemoxyNov 11th 2010 2:21PM
Yes, the fonts are still messed up. It sucks that I have to turn off hardware acceleration and not get to enjoy it.
