Mozilla released its latest browser update, Firefox 47, on June 7, 2016. This is the fourth rapid release browser update in 2016. There are no new features that you will see in the front-end since most changes have taken place in the back-end.
First of all, Mozilla has once again pushed the Extension Signing enforcement to possibly Firefox 48. This means that if you have any Firefox add-ons that were disabled by default, you can use the manual override. You can do using the “about:config” option and changing the “xpinstall.signatures.required” preference to “false”.
As a security and stability measure, Mozilla has removed the whitelist for plugins. Therefore, all plugins (with some exceptions) will be set to click-to-play giving more control to users.
The session restore Firefox preference value has been set to “True” by default. With this change, when you start or restart your browser, it will limit multiple tabs from loading simultaneously. This change will improve browser startup time.
You will find a new internal page “About:Preference” which will help you check performance of add-ons as well as open tabs. Embedded YouTube videos will now play using HTML5 video, if Flash is not installed.
And finally, Mozilla has added support for Google’s Widevine CDM (Content Decryption Module). This enables playback of HTML5 video content that requires DRM (Digital Rights Management). So these were the major updates and changes that made their way Firefox 47.
There were some other change as well as a few changes for Developers. You can check the release notes in the link provided below.
