Improved Preformance and Privacy in Firefox 21.0 |
Mozilla has released Firefox 21.0 Final, a major new version of its cross-platform, open-source web browser for Windows, Mac and Linux. Version 21 gives users more control over their tracking cookie preferences, extends the social API to support four new providers and implements support for tools to help with troubleshooting and performance issues.
Also included in this release are improvements to its Do Not Track Feature, users now have three options via the Privacy tab of Firefox’s Options dialog. The default "user says nothing" and "user says don’t track" have now been joined by a "Tell sites that I want to be tracked" option for those who wish to allow tracking in order to see more personally relevant advertising.
Mozilla has also improved Firefox's Social API to support new providers. Users now have the option to add Asian social providers Mixi and Weibo, plus news aggregators msnNOW and Cliqz. Once installed, users switch between providers by clicking the main button and selecting the chosen provider from the list.
Lastly is this author's personal favorite the new Firefox Health Report. A tool that provides information designed to improve browser performance while also sharing data with Mozilla, This can be disabled for those that do not wish to share data with Mozilla, Options dialog -- select Advanced > Data Choices tab to do so. Firefox will also monitor start-up times and alert users via the status bar of slow start times and offer a link to a web site which will offer advise on how to improve start up speed.
Version 21.0 update also comes with the promise of improved graphics performance, the implementation of Remote Profiling for developers and the removal of support for certain depreciated History APIs as part of Firefox’s drive towards asynchronous History and Bookmarks.
