TinyURL by Robert A Moreno II

This extension uses tinyurl.com or is.gd to create a tiny URL from today's ridiculously enormous URLs that frequently fail when launching from email clients and other URI enabled software.

With one click, the URL from your active tab will be sent to the selected URL shortening service, returning the tiny URL directly in to your clipboard, ready for pasting.

There is no extra clicking, and (optionally) no notifications. As soon as you click the icon, you can paste the tiny URL where you want it.

Notes about permissions:

Get data from the clipboard
This permission was added to support a requested to generate a shortened URL from a link already copied to the clipboard. It gives the add-on the ability to read from the clipboard for this purpose.

Input data to the clipboard
This permission was added to support programmatically copying the shortened URL to the clipboard. It gives the add-on the ability to write to the clipboard for this purpose.

Access browser tabs
This permission was added to support a requested to generate a shortened URL via the context menu on any open tab. It gives the add-on the ability to add context menus to tabs for this purpose.

Access your data for all websites
The design goal of this add-on was to have a truly one click experience. I originally made this for my own personal use and it didn't even have notifications. When it was published as an add-on, I received many requests to add some kind of indication that the link was copied to the clipboard. Most other add-ons opened some form of popup from the add-on button, and you need to take action (usually another click somewhere) to close them. To keep with the original intent of being a truly one click experience, I had to added support for notifications using the least intrusive notification I could think of, which was an HTML modal formatted by CSS and controlled by JavaScript. To open a modal and pass information to it, I need to add it to the active website's DOM. This permission gives the add-on the ability to add the notification as a modal to the current webpage DOM.
