Append Domain автор Richard Adenling

This extension adds "- www.currentdomain.ext" to the title of all open tabs. This is useful if you're a Keepass user and would like to use the autotype feature. It determines which password to use based on the window name and by adding the current domain at the end of the page title, there will always be something in the window title to match against.

About the extension
The extension is minimalistic and without any configurable options. For each page you open, it adds the current domain to the title. Whenever the page title changes, it attempts to re-append the domain.
