How to set up firefox to only look up address bar pop-down hint bookmarks in specific folders?

Question

By default today Firefox versions use whole bookmarks and history databases to suggest items in a drop-down list when I write an URL manually.

I'd like to limit the suggestions base with just some (or one) specific folders in my bookmarks. How can I achieve this?

Don't think you can selectively disable bookmark folders, but turning off autocomplete from bookmarks completely is possible via browser.urlbar.default.behavior configuration parameter. You can read more on this here.
