I can't even tell if it works or not, because the extension simply choked when I clicked on it. Maybe it works when there is just a few bookmarks, but I have many thousands, and it seems to try to process them all every single time it's invoked, instead of generating a data base cache or whatever. Unusable!

Sorry not working good also has Poor design and not showing Bookmarks Correctly and clearly, Honestly I thought it updates Favorites icons that are imported.
Romving it ...

This doesn't tell you that what it does is create a sub-toolbar of tiny bookmark icons, just below the tool icon in the tool bar.
