Firefox 47.0 released with bugfix and how to install on ubunto OS

Mozilla Firefox 44.0.2 was recently released by Mozilla team. This latest release primarily focuses on bugfix. A notable update to this release is it fixes an issue where Firefox hangs or crashes on startup.

New Features in Firefox 47

Since you’re nosey (like us) you want to know exactly what’s changed. We can help you out there.

Firefox 47 can play old YouTube video embeds in HTML5
when Flash is not installed.

Don’t misunderstand this change; I know you’ve watched HTML5 YouTube embeds in Firefox for a long time.

This change is specifically that Firefox is now able to “convert” ye-olde YouTube Flash embeds to HTML5 ones so that you can view them.


On the topic of HTML5, Windows and Mac users can now watch HTML5 video content wrapped in DRM thanks to Firefox adding support for Google’s Widevine CDM. This allows sites like Amazon Prime Video and Netflix to stream DRM-protected video using HTML5 and not a third-party plugin (die, Silverlight, die).

‘Why not Linux?’, you ask. And on that I’m not too sure on.

Google Chrome (not Chromium) for Linux support comes with Google Widevine CDM built-in, which is how you can watch Netflix on Linux using Chrome but not Chromium.
The way Firefox hooks into the Google Widevine CDM could be limited to interfaces/APIs that are only exposed through the binary Windows and Mac versions. It could be that Linux support for Google’s CDM is to follow in future. It could be that you’re better at researching this specific implementation than I am and so you can shed some light on it in the comments.

Other notable changes in Firefox 47 include:

• Enable VP9 video codec for users with fast machines
  
• Embedded YouTube videos now play with HTML5 video if Flash is not installed.
  
• View and search open tabs from your smartphone or another computer in a sidebar
  
• Allow no-cache on back/forward navigations for https resources
  
• Latgalu [ltg] locale added. Wikipedia tells us there are 164,500 daily speakers.
  
• User-agent spoofing in responsive mode
• Service workers and Push API debugging
• Security & bug fixes

See the official release notes for Firefox 47 for further details on the changes present.
