how can I save bookmarks to more than one folder?
I have a lot of saved bookmarks, organised into a meaningful arrangement of folders and sub-folders.
Many times I would like to save a bookmark to more than one folder but when I try to do that Firefox only deletes the bookmark from the first folder then I can save it to a different one.

You can do a Copy & Paste in the Bookmarks Manager (Shift+Ctrl+B) to create a copy of a bookmark.
You can also drag the site favicon on the left end of the location bar to a folder in the Bookmarks menu drop down list or to a folder in the side bar (Ctrl+B) or to the Bookmarks Toolbar.
In the side bar you need to click to the left of the icon to prevent Firefox from opening the bookmark.
