Rated 3 out of 5 stars
Installed this addon as a replacement for the Multirow Bookmarks addon that has now incorporated 'sponsored ads' in it with no way provided to disable those ads. So far I am happy with this addon, though I am a little confused as to why I have a 'show more bookmarks' button showing up even though I have a vertical scrollbar that allows me access to all of my bookmarks anyway. To me I think there should be an option to disable the 'show more bookmarks' button if I want to (especially since like I said there's already a vertical scroll bar there that lets me access all of the bookmarks anyway).
Edit: Since restarting Firefox, I no longer have the 'Show more bookmarks' button I mentioned above, not sure why it was there before but not now.
