It saves all the information of a website if needed, including links and hypertext. The only minus is: unHMTL or MAFF also saved the address of the original webpage. In "Save page WE" I cannot find this.
If you want to automatically display the address of the original web page when the saved page is opened, then enable the 'Include information bar at top of page' option.
Alternatively, you can use the 'View Saved Page Info' button/context menu command to display a lot of information about the saved file, including the address of the original web page.
