If you attempt to use the Toolbar Share feature to share a webpage on Twitter.com, the link you want to share may not appear in the "What's happening?" text field on Twitter. We are aware of this issue and will be automatically updating users with a fix in the coming weeks.
As a workaround, try the traditional copy (Ctrl+C) and paste (Ctrl+V) method to copy the link you want to share and paste it to the "What's happening" text field.
