New icons with support for dark themes. Toolbar icons are now semi-transparent black or white depending on
browser theme. Should look better in most themes.
Put the icon in the tab-strip by default. This only affects new installs, but you can move the icon to the tab-strip yourself by right-clicking the toolbar and selecting “Customize toolbar”.

Add keyboard shortcut support. Default keyboard shortcut is Alt+Shift+R, can be redefined in the extension settings.

Rewritten for the new WebExtensions API. Changed home page to https://github.com/mikl/browser-go-to-random-tab

Only compatible with Firefox 48.0 and newer, use version 1 if you need and older version.
