In a strong, head-held-high missive, Adobe has detailed a new initiative to bring Flash local storage clearing to Web browser UIs. The new API, NPAPI ClearSiteData will let Firefox and Chrome users clear Flash's Local Shared Objects, or 'Flash cookies,' in the same way that you currently clear cookies and temporary Internet files.

LSOs are very commonly used throughout the Web, but unlike conventional cookies they're a little harder to delete. A lot of websites use them to track you across the Web, but they're also used by sites like YouTube to store your video preferences.

When Google began working on a built-in Flash plug-in for Chrome, they cited a handful of key motivations. They wanted a more hassle-free web experience for end users, more modern alternative to the aging NPAPI architecture, better security, and an easier way to deliver updates.

According to the SecBrowsing blog, their update aspirations have been a smashing success.

The traditional Flash updater is easy enough to avoid -- I often work on end users systems and see the beleaguered Flash updater crying out for attention from the system tray. Sadly, its cries often go ignored. Chrome's internal updater, however, can't be ignored. When there's a update to the browser or an internal plug-in, by Odin's beard, you're going to get it!

Within just two days of the most recent Flash update, fewer than 30% of SecBrowsing visitors were running an out-of-date version. That's compared to 14 days with the previous release -- a substantial improvement.

No comparisons to other browsers are given, but I've got to think that Chrome users are well ahead of the curve here.
