I have something whose icon looks like a 2-legged table that I got from the menu. The bookmarks appear in the sidebar, but I can't do anything like renaming, moving or removing. I downloaded an other extension called "V7 bookmarks," but it blanks out the sidebar completely.
I don't know what Speed Dial does. It just produces a blank page when I click it.
This browser has become a disappointment. The manual is missing so many things. It had been so easy to use a few years ago, more intuitive and with fewer "improvements." It's going the way of Firefox.
