An anonymous reader quotes a report from VentureBeat: Mozilla today launched Firefox 47 for Windows, Mac, Linux, and Android. The browser has gained a sidebar for synced tabs from other devices, improvements to YouTube playback and HTML5 support, and is seeing the end of support for Android Gingerbread. [If you’re logged in with your Firefox Account, the sidebar will show all your open tabs from your smartphone and other computers. The sidebar even lets you search for specific tabs. Next, Firefox 47 supports the open source VP9 video codec on machines with powerful multiprocessors. VP9 is the successor to VP8, both of which fall under Google’s WebM project of freeing web codecs from royalty constraints.] Firefox 47 is available for download on Firefox.com, and will be slowly released on Google Play. You can view the full Firefox 47 changelog here. If you’re a developer, Firefox 47 for developers offers more details for you.
