See the little earth icon in the URL box? Left Click and HOLD, then drag it to the bookmark bar and 'drop' it where you want it to be. You can put it on the bar itself, or into a 'folder' that you have created. I use folders so I can have places to put the bookmarks without running out of room.
To 'edit' it once made, find it, right click on it, chose EDIT from the popup menu, and edit to your hearts content. OR open the Bookmark manager under the TOOL, and edit it there.
OR click the Star at the left end of the URL bar and 'browse to where you want to put it.
Again, 'edit' as above.
