This update is available for Google Chrome and Mozilla Firefox. Chrome users should see the extension update itself automatically within the next 60 minutes.
Note for Firefox users - you must manually update by redownloading the extension at
http://www.enhancedsteam.com/download/. This version includes auto-update functionality for future releases. Additionally, some features of Enhanced Steam are not yet working with versions of Firefox less than version 50. For example, custom profile backgrounds and Early Access banners aren't working from steamcommunity.com pages. Most of these features are re-enabled by using Firefox 50 or above, or will be re-enabled at a future date.
As always, please let me know if you encounter any issues with this release.
