After updating Google Chrome on iOS, users can head on over to the menu tab (top right), tap Share, and the tap the More button. This will bring users to a menu where anyone can enable or disable third-party App Extensions. After enabling a few, going to the Share menu will now show sharing options for whichever apps were enabled previously.
This is a great feature since this means Chrome will no longer be limited to sharing only on Facebook and Twitter social networks. As soon as developers update apps with third-party App Extensions, more sharing websites will be implemented for use with Google Chrome.
