What’s New in Firefox 4:

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.

Annunciato il rilascio della prima release candidate di Slackware linux 13.37

Hey folks, I think it's time for Slackware 13.37 (hopefully this helps to make up for our lack of code names) release candidate 1! After a lot of testing and consideration, we've decided to go with the recently released 2.6.37.3 Linux kernel which seems to work best for X, contains support for Speakup, and looks like a better kernel branch to be using as we move forward. Please test so we can have a stable release soon.
