As expected, Mozilla has now released its latest Firefox 4 Beta 11 with a number of performance and stability tweaks building on last month’s 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.
Enhanced Privacy with ‘Do Not Track’
The ‘Do Not Track’ feature is a significant step forward in user privacy. This functionality allows users to send a signal to websites indicating that they do not wish to be tracked. This is particularly important in an age where online privacy is a growing concern. Advertisers often use cookies and other tracking methods to monitor user behavior, which can lead to targeted advertising. While this can be beneficial for advertisers, it raises privacy issues for users who prefer to keep their online activities private.
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
Performance and Stability Improvements
In addition to the ‘Do Not Track’ feature, Firefox 4 Beta 11 includes several performance and stability improvements. These enhancements are designed to make the browser faster and more reliable. For example, the new beta version includes better support for WebGL, which allows for 3D graphics to be rendered in the browser without the need for additional plugins. This is a significant improvement for developers and users who enjoy rich, interactive web applications.
Moreover, the new beta version has improved JavaScript performance, which is crucial for modern web applications that rely heavily on JavaScript for functionality. Faster JavaScript execution means that web pages load quicker and respond more smoothly to user interactions.

Another notable improvement is the enhanced support for HTML5. As the web continues to evolve, HTML5 is becoming increasingly important for creating rich, multimedia experiences. Firefox 4 Beta 11’s improved HTML5 support ensures that users can enjoy the latest web technologies without compatibility issues.
In conclusion, Firefox 4 Beta 11 is a significant update that brings several important features and improvements. The ‘Do Not Track’ functionality is a major step forward in protecting user privacy, while the performance and stability enhancements make the browser faster and more reliable. As Mozilla continues to refine and improve Firefox, users can look forward to an even better browsing experience in the final release.
