I am a newbie and I like this very much - more later

Almost perfect! The one thing it doesn't do is fireoff bookmarklets. My bookmarks bar solely consists of bookmarklets; I was hoping to save screen real estate, but this won't do.

The developer has already responded to an earlier review, this isn't possible in FF. If it ever is I'll reinstall.

It works great with http: links, but not file: links, bookmarklets or javascript. The bookmark icon handles these fine. But this is the only addon that reduces "screen real-estate" so I'm going to use it.
Firefox 57 was not really ready for prime time. I'm thinking of returning to 56 or even Chrome until they get this hog working nicely.

Nice plugin! Almost all that I wanted since Google Shortcuts got deprecated.

Appears decent - perhaps the only viable replacement at present for the addons that compressed the bookmark bar into a clean set of unlabelled icons.
Except that it does not respect the configuration that tells bookmarks to open in a new tab rather than the current one. Also, the lack of icons is a bit annoying, though I assume that is a forthcoming feature.

Would there be a way to not have all the folders expanded? Right now the list of bookmarks in that box is quite long...
