New Tab Redirect — Irvirty

To set up your website URL to open in a new tab page whenever you create one, you need to enter the URL address in the add-on options. Once you've done that, simply press the "+" button to create a new tab (or use the Ctrl+T shortcut) and your website will open automatically.

How the addon works:
1. When you open a new tab, the addon page opens.
2. The addon redirects to the page specified in the settings (it creates a new tab and closes itself; it's fast).
3. Done; you should theoretically be on your page.
