What is a Pop-Up Blocker and how do I deactivate it?
A Pop-Up Blocker is a function which prevents an additional browser window - a so-called pop-up - from opening or 'popping up'.
Deactivation using Microsoft Internet Explorer
The enhanced Internet Explorer with Windows XP Service Pack 2 contains a Pop-up Blocker. To allow pop-ups from Lufthansa, select the menu items 'Tools' - 'Pop-up Blocker' - 'Pop-up Blocker Settings'. Then under 'Address of website to allow' enter the following domain: LH.com and click 'Add'.
Deactivation using Mozilla Firefox
The Mozilla Firefox browser comes with a built-in live Pop-up Blocker as standard. To allow pop-ups from Lufthansa, select the menu items 'Tools' - 'Settings'. Under 'Content' add the following domain via the 'Allowed sites' button: LH.com.
