YOURLS is an URL shortener, just like bit.ly or goo.gl, but you are allowed to install your own private instance. So you can diminish the tracking of these big platforms ;-)
This piece of software is an extension for the browser Firefox that let's you quickly shorten the URL of the website you are just visiting. All you need is a Firefox and an installation of YOURLS. You can also find this plugin at Mozillas addon service platform.
This add-on for the Firefox consists of three modifications of your browser overlay:
The setup can be done in the Add-ons Manager (browse to about:addons). Click on the Preferences button next to the YOURLS shortener entry and you'll see a window like this:
Following values should be provided:
API URL: The URL to your YOURLS installation. In my case it's https://s.binfalse.de/
Signature: The signature of your account. You will find this string on the Tools page in the Secure passwordless API call section. This string is not required for public YOURLS installations.
Ask for a keyword? Should the extension ask for a keyword before shortening? If this box is checked you'll always be asked like this:
Not providing such a keyword has the same effect as unchecking the box: The API will decide about the short URL.
