As expected Mozilla has now released its latest Firefox 4 Beta 11 with a number of performance and stability tweaks building on last months Firefox 4 Beta 10 release and edging ever closer to a final release candidate.
One new feature worth a mention though is the new ‘Do Not track’ functionality added to this release to protect user privacy, allowing users to opt-out of behavior tracking by advertisers through cookies and other browser-based methods.
Mozilla privacy lead Alex Fowler explains:
“When the feature is enabled and users turn it on, web sites will be told by Firefox that a user would like to opt out of OBA,” … “We believe the header-based approach has the potential to be better for the web in the long run because it is a clearer and more universal opt-out mechanism than cookies or blacklists.” Full Blog post
