Private browsing will now extend to the Flash plug-in with Flash Player 10.1 Adobe have announced.

“Integrating with your web browser, Flash Player 10.1 will automatically clear stored data in accordance with your browser’s private browsing settings” said Adobe Engineer Jimson Xu.

Flash Player 10.1 supports private browsing with Internet Explorer 8+, Mozilla Firefox 3.5+, and Google Chrome 1.0+, with Apple’s Safari 2.0+support coming soon.

Missing from this list is Opera, which has only recently included private browsing in the latest 10.50 alpha release.

Adobe Flash Player 10.1 is currently in Beta and is expected in the first half of this year. Beta 2 can be downloaded from Adobe Labs.

Private browsing mode has been included in the latest nightly release for Firefox 3.1 beta. This is a feature which didn’t quite make it into Firefox 3.

Private browsing allows you to browse the web “anonymously”. No cookies, cache, history, temporary files, or saved passwords will be stored while in private mode.

To turn on private browsing, go to Tools –> Private Browsing. You can download the latest nightly Firefox 3.1 beta build here.
