Apple updates Safari 5; users can add new features through Safari Extensions Gallery

Apple today released Safari 5.0.1, turning on Safari Extensions and introducing the Safari Extensions Gallery. Apple introduced extensions support in Safari 5 in June so developers could begin creating extensions with HTML5, CSS3 and JavaScript web standards. With Safari Extensions Gallery, users can quickly find extensions that add powerful new features to Safari, from toolbars that display live web feeds to sophisticated programs that filter web content. Safari 5.0.1 allows users to download and install extensions either from the Safari Extensions Gallery or directly from a developer’s site.

“Safari 5 has been a big hit, and user response to the innovative new Safari Reader has been fantastic,” said Brian Croll, Apple’s vice president of OS X Product Marketing, in the press release. “We’re thrilled to see so many leading developers creating great extensions and think our users are going to love being able to customize Safari.”

“Millions of our customers already use Amazon Wish Lists to store items they want to buy for themselves or receive as gifts,” said Gianna Puerini, vice president of Worldwide Design and Community at, in the press release. “With Safari 5, we were able to quickly build the Add to Amazon Wish List extension that lets customers add items from any website to their Amazon Wish List with the click of a button.”

“We’re excited to continue working closely with Apple to bring visually compelling Bing experiences to Safari,” said Jeff Henshaw, general manager of Bing User Experience, in the press release. “The Bing Extension for Safari brings Bing search intelligence to everyday browsing with Safari. When a user selects text in Safari, Bing instantly recognizes what they might need and pops up helpful, informative tips, from real time maps and driving directions to real time translations to direct web search results.”

“Using web standard technologies and Safari’s extension builder, we developed an extension to give fans another way to consume up-to-the-moment baseball content, including live look-ins to games, right from the Safari toolbar,” said Noah Garden, executive vice president, Commerce and Sponsorship at, in the press release.

MacDailyNews Take: “MLB Toolbar.” Wherever A-Roid goes for drinks.

“Our extension for Safari is a great way for readers to get all of the latest breaking news and all the important stories, blogs and columns they want to see,” said Denise Warren, general manager, at The New York Times Company, in the press release. “While you browse other sites in Safari, our extension checks for updates and slides in new headlines and thumbnails, so you won’t miss a thing.”

“Creating our Twitter extension in Safari couldn’t have been easier,” said Jason Goldman, vice president of Product at Twitter, in the press release. “By providing features like the ability to tweet about a page and view trending topics, we’ve created a simple way to deliver relevant, interesting content to people regardless of where they are on the web.”

The Safari Extensions Gallery is accessible from the Safari menu or at Users can download and install extensions from the gallery with a single click, and there’s no need to restart the browser. Extensions can be automatically updated and are easily managed within Safari. Users can enable or disable individual extensions, or turn off all extensions with one click.

Safari Extensions are built with HTML5, CSS3 and JavaScript web standards, and can have all the power and functionality of advanced web applications. Every Safari Extension is signed with a digital certificate from Apple to prevent tampering and to verify that updates to the extension are from the original developer. Safari Extensions are sandboxed, so they can’t access information on a user’s system or communicate with websites aside from those specified by the developer. For increased stability, Safari Extensions run solely in the browser.

Safari 5 also features Safari Reader, which presents single and multipage articles on the web in a new, scrollable view without distracting content or clutter. The Nitro JavaScript engine runs JavaScript up to 30 percent faster than Safari 4.* Built on the open source WebKit engine developed by Apple, Safari 5 includes more than a dozen powerful new HTML5 features for creating media-rich experiences, like full screen playback and closed captions for HTML5 video.

Safari 5 is available for both Mac OS X and Windows as a free download at Safari 5 for Mac OS X requires Mac OS X Leopard 10.5.8 or Mac OS X Snow Leopard 10.6.2 or later. Safari 5 for Windows requires Windows XP SP2, Windows Vista or Windows 7, a minimum 256MB of memory and a system with at least a 500 MHz Intel Pentium processor.

  1. Safari needs TOOLBARS to compete with Firefox? Don’t think so.
    I just saw a write-up on Tab Joy(?), a feature soon to be brought to Firefox, that will help make Firefox MUCH more usable than the other browsers out there. There seem to be two major concepts involved – the ability to group Tabs together (naming groups is optional, switching groups at will, moving Tabs between groups when desired) and sharing Tab groups with others.
    The only problem I see with this might be memory constraints. Sure, the unused groups could be swapped out while not in use, but that would lead to speed issues when attempting to access that set again. Still … a Mac can hold a whole chunk of RAM – at least, a POWER MAC can. ” width=”19″ height=”19″ alt=”wink” style=”border:0;” />

  2. @ Al

    We support roughly 8,000 Macs (education) and none of them experience freezes, crashes or lockups unless the computers are broken (defective hardware/corrupted software).

    I’d suggest you get your system looked at, ‘cos you’re living outside reality if you’re blaming Safari for your woes.

  3. BUG — quit Safari before running the installer otherwise you’ll get caught in an endless loop: “Please quite Safari before beginning this update” click OK “Please quite Safari before beginning this update” click ok “Please quite Safari before beginning this update”……
