Sometimes you want to use multiple websites in the same session. (for example if you have a session for Facebook and you would like to use another website with the same Facebook login) You can achieve this with the following steps:
1. Search for the base session and open session settings:
2. Open the Websites tab
3. Click Add and enter the url of the additional website
4. Click the Add button in the dialog and the new website will appear in the SessionBox menu under the same session name
Tipp: The Add dialog autofilled with the current tab's url. If you don't want to type the url just open the website before you start the process.
