Apple Releases Safari 5

By June 8, 2010

Follow me on:

Apple released Safari 5, bringing speed, security, and a wagonload of new features and capabilities to your Mac (or Windows PC). Speed improvements allow Safari 5 to run JavaScript about 30% faster than Safari 4, and push performance past the recently released Google Chrome browser by around 3%. The speed improvements come from improving and fine-tuning the Nitro JavaScript engine, and improving the caching and DNS pre-fetching systems.

Safari 5 now supports extensions, giving developers and web site builders the ability to add customized browsing tools and features. Safari extensions run in a special 'sandbox' that prevents the extensions from accessing system resources, or being used to gather information on the user. All Safari extensions must carry an Apple-provided digital certificate to ensure the extension is from the source it claims to be from, as well as protect the extension from unauthorized attempts to update it or change its behavior.

Another interesting new feature of Safari 5 is the Safari Reader. When Safari detects that a web page contains a single article, the Safari Reader button becomes available. When you select the button, the page will display the article in larger text, with ads and other clutter removed.

My favorite change in Safari 5 is the return to the progress bar seen in Safari 3 and earlier. The address bar now shows the progress of a page being rendered as a blue bar that fills the address field.

Safari 5 includes 48 security updates, some of which have been around for a while, including a fix for an issue with HTML buttons that could allow hackers to run arbitrary code.

Apple also released Safari 4.1 for Tiger. It includes all of the security updates as well as many of Safari 5's features.

Safari 5 is available from the Software Update item under the Apple menu, or directly from the Apple web site.

So how will these extensions be made available? Firefox has a dedicated web page for all their add-ons.

I’d love to try it out if only it wouldn’t keep crashing. How do we go back to 4?

YouTube works for me on Safari 5, as are a number of photos I tried. I uninstalled Glims and that fixed the crashing.

MAYDAY MAYDAY!!! Safari 5 does not work with 1Password! Hold off upgrading until we find out more. I’ve already uninstalled Glims and that stopped the crashing, but now I have to, once again, struggle along with Firefox because I use 1Password all the time.

Hi Jack,
Apple will have a ‘Safari Extension Gallery’ on its web site. As far as I can tell, Apple will add the Safari Extension Gallery in the late summer. Until then, you will see extensions available directly from the various developers.
Panic, an Apple developer, was one of the first to release a Safari Extension. It’s called Coda Notes, and you can take a look at it on the Panic web site: http://www.panic.com/blog/2010/06/coda-notes-previe/
