Re: Where can I find deleted bookmarks? where do they go? I want to delete them completely. Ed.
The bookmarks are stored within a file called places.sqlite which is a database, so this is changed, an individual bookmark is not stored as an html file. In addition Firefox makes some backup files automatically of with the name bookmarks, a date and the extension .json.
If you delete a bookmark from your library it will still exist for a while in the bookmarks backup. Additionaly a record of the site visit will be held in the History unless you visited whilst using Private Browsing.
If you were to delete places.sqlite note you would loose History as well as ALL your own bookmarks, including any tags keywords folders and descriptions.
Not sue whether that answers your question fully as I am not too sure what you may wish to achieve. Has something happened that you wish to prevent?
Depending on what you are trying to do some of these may be worth reading:
