Mozilla Releases Firefox 64-bit for Windows

Mozilla this week released a version of its Firefox browser that's optimized for those with 64-bit Windows systems.
Firefox 64-bit for Windows works on Windows 7 and above and is available on the Firefox All Systems page.
Mozilla said the upgrade should result in "added performance for applications and games." Don't be surprised, though, if certain sites requiring plugins that worked in previous 32-bit versions don't work in Firefox 64-bit for Windows.
In October, Mozilla announced plans to end support for the aging Netscape Plugin Application Programming Interface (NPAPI) by the end of 2016. Once essential to the Web experience, NPAPI has been replaced by streaming video, advanced graphics, and gaming features.
Also this week, Mozilla rolled out more user control over how data is shared in Firefox; folks can now block additional trackers in Private Browsing with Tracking Protection.
Introduced in early November, the Windows, Mac, Android, and Linux-based program prevents sites from gathering data about your Web activity. While browsing in a private window, it blocks ads, analytics trackers, social share buttons, and other content that may record behavior without your knowledge.
