Flash, Firefox Play Together in New Security ‘Sandbox’
Adobe has released Flash Player 11.3, which offers several new features aimed to make the widely used browser plugin more secure — including a new security “sandbox” for Firefox on Windows.
To grab the latest version of Flash, head to Adobe’s Flash Player download page.
The big news in this release is the new sandbox security settings for Firefox on Windows, which first showed up in the beta release earlier this year. Flash’s near ubiquity make it a popular target for web-based attacks, but the new sandboxing means that even when such attacks succeed the damage is limited and won’t spill over into the rest of the browser or even the operating system.
Adobe and Google have previously worked together to add the same sandboxing feature to the Chrome browsers.
Mac users finally get an (optional) background updater with Flash 11.3. It works just like the updater that’s been available in Windows for some time — provided you allow automatic updates, the new updater will check with Adobe’s servers every 24 hours. If an update is available, the background updater can download and install it without interrupting your browsing session.
This release of Flash for OS X is also the first to support Apple’s Gatekeeper feature coming later this year in OS X 10.8. Gatekeeper checks a developer’s unique Apple Developer ID to verify that an application is not known malware. Flash 11.3 for OS X is the first release signed with an Apple Developer ID certificate, ensuring there will be no problems installing it on OS X 10.8.
