If you select add to favourites then you can quickly access it by selecting the favourites menu in the top bar.
If you want to add a separate folder into the favourites then you can either do this when you add a page to favourites or by selecting organize favourites from the favourites menu.
Why not create a folder in documents, then re-name this 'new folder' to 'Menus' for instance.
Then all you need do is go to the page where your menu is, then right click and select 'save page as', you can then select your new named folder and click 'save'
The Favorites folder is there for Internet saved shortcuts. Always has been.
It is called Bookmarks in Firefox.
If you look at Start Menu properties, you can add the Favorites folder there, so you can browse off the Start menu and select any of them to open a browser and go to the page.
I wouldn't start making one anywhere else!
