Internet Explorer 6 used to have a FrontPage button on the menu bar but is missing in IE7.

Solution:

An "Edit with Microsoft Office FrontPage" has been relocated to the page submenu. This probably because Microsoft has announced that it will discontinue release of new versions of the product.

Here's How:

1. Navigate to the desired page for editing
2. Click the Page Icon located on the right in the new Command Bar
   
3. Select "Edit with Microsoft Office FrontPage"
4. FrontPage should open as usual.
