Do they come back if you click a bookmark in the drop-down list?

They do, but I have so many that it would be too time consuming. They will again go away when I run a cleanup program. I would like a way to get them all back at one time.

Favicon Reloader

About this Add-on
A small tool to reload Favourite icons

It finds bookmarks without Favorit Icon and tries to fetch them from their web site.

After installation you will find the addon in the bookmark menu and in the context menu.

Which cleanup program do you use and what data is cleared?

I use spy hunter

It is best to exclude the Firefox program folder from such programs to avoid dataloss or otherwise issues with corrupted files and if necessary use built-in means to clear personal data.
