url-rotation od NicoVIII

With this addon you can define a list of urls which the extension will show one after another after you start it by clicking on the extension icon in the browser bar. The extension opens some tabs which are used to preload the upcoming urls. After a configured amount of time the active tab changes and shows the next url.

You can stop it anytime through the same icon you used to start it and it will stop automatically if you close one of the managed tabs or change to a non-managed tab. When the extension stops it will remove the tabs it opened automatically.

You can define some settings like the used urls and the frequency of the url change in the extensions settings page.
