Firefox 20 released – What is new?

Mozilla has finally rolled out the 20th edition of their popular browser Firefox. Following the rapid release cycle, the 20th edition goes live after testing of six beta’s. Previously 19.0.2 was the stable release. The latest version available is Firefox 20 and the download links remain the same.


Here are the highlights of 20th release:

  • Ability to close hanging plugins, without the browser hanging
  • Firefox will offer to reset the Awesomebar search provider
  • New download panel
  • Continued performance improvements in page loads, downloads, shutdown, etc.
  • Continued implementation of draft ECMAScript 6 – clear() and Math.imul <canvas> now supports blend modes
  • Various <audio> and <video> improvements
  • getUserMedia implemented for web access to the user’s camera and microphone
  • Details button on Crash Reporter
  • Unity plugin doesn’t display in HiDPI mode.


There are some performance improvements, as usual, and some new features under the hood for developers to use. Per window private browsing makes it possible to open a private browsing window without closing all of your existing tabs. This may not seem like much, but having to switch back and forth between private browsing and regular browsing was an annoying limitation, one that led a lot of users to stop using the feature altogether. Likewise the new download panel – it may not be a hugely important feature, but this is the first major improvement to the download manager since Firefox was introduced. The new panel is part of the toolbar, it pops up when you use it, it has a download time estimate, overall, it’s fairly useful though something that should have been implemented for years now.
