Fastest Firefox Ever
- Performance: Firefox is up to six times faster than the previous release. With improved start-up and page load times, speedy Web app performance and hardware accelerated graphics, Firefox is optimized for rich, interactive websites.
Streamlined Interface
- App Tabs: give a permanent home to frequently visited sites like Web mail, Twitter, Pandora, Flickr.
- Switch to Tab: easily find and switch to any open tab from your Awesome Bar without opening duplicate tabs.
- Panorama: drag and drop tabs into manageable groups to save time while navigating many open tabs.
Private and Secure Synchronization
- Firefox Sync: access your Awesome Bar history, bookmarks, open tabs, passwords and form data across multiple computers and mobile devices.
Most Customizable
- New Add-ons Manager: easily discover and install more than 200,000 add-ons to customize the features, functionality and look of Firefox.
Private and Secure
- Do Not Track: Firefox is leading the Web towards a universal standard Do Not Track feature that allows users to opt-out of tracking used for behavioral advertising.
- Firefox puts privacy first, fixing flaws in some Web standards to prevent others from accessing your browser history.
- HTTP Strict Transport Security (HSTS): automatically establishes secure connections to stop “man in the middle” attacks and keep sensitive data safe from interception during the log-in process.
- Content Security Policy (CSP): prevent cross-scripting attacks by allowing sites to explicitly tell the browser which content is legitimate.
Cutting Edge Tools for Web Developers
- The JavaScript engine incorporates the new JägerMonkey JIT compiler, along with enhancements to the existing TraceMonkey JIT and SpiderMonkey’s interpreter for faster page-load speed and better performance of Web apps and games.
- HTML5 support in Firefox includes hardware accelerated, high-definition video (WebM), 3D graphics, offline data storage, professional typography, touchscreen interfaces and the Mozilla Audio API to help create visual experiences for sound and more.
- Firefox 4 also improves existing tools like CSS, Canvas and SVG to enable developers to make exciting Web pages.
- Firefox provides uninterrupted browsing when there is a crash in the Adobe Flash, Apple QuickTime or Microsoft Silverlight plugins. If one of these plugins crashes or freezes, it won’t affect the rest of Firefox. Simply reload the page to restart the plugin.
Been playing with the betas and stuff, it's pretty good but I keep going back to Chrome.. at some point they fixed the 2.5GB memory usage problem I seemed to have so there's nothing against Chrome for me now.
EDIT: Except printing, I still use FireFox to print images from web pages for my kid because it has a print-preview and lets me scale it.
I just installed it to see what it was like, but I doubt I'll be switching back from Chrome. I fought like hell against switching to Chrome in the first place, too.
I hate downloading through Chrome. Not sure if there are settings I haven't played with, but I like using Firefox for downloads more than seeing the colored bar at the bottom of the screen and the rest of the Chrome download experience.
I have a problem. Got a new work PC and downloaded FireFox 4. The at symbol comes up as ", number symbol is /, and the up arrow is ?. I also just noticed that most of the punctuation is all messed up. This isn`t a windows issue and everything is fine in office. I have tried playing with the character encoding options but nothing seems to make a difference.
Any ideasÉ ... wtf, that`s supposed to be a question mark.

I am going to give this a try due to a pretty much constant flash crash with Chrome. I don't particularly want to go back but this issue is freaking annoying.

I'm having constant Flash crashes in FF3. Stupid Flash.
Well firefox 4 isn't for me. It reset all my settings and when I tried to change them back, it makes me look up every password and moniker I need to sign in on every site every time. I'm back to 3.6 but now I have to reset that too.
I was liking firefox beta 4 until youtube / video streams became terrible and unwatchable. Not sure if this would be fixed in the real Firefox 4. I've since added google chrome and opera to my repertoire of browsers.
As soon as I fixed all the visual changes...I decided I love FF4. A huge upgrade on speed for me (I wonder if it'll have problems with my 6 year old laptop though...)
